hotswapping usb
I've lost my ability to hot swap usb2 devices after using them
successfully for several years. If they are connected on power up they work fine and there is the disconnect icon for when I want to disconnect them. This works ok. I can disconnect and carry on normally. However I can't plug in a usb device while the pc is up and running - it freezes up. There are no problems reported in my Devices, Properties menu. I suspect some software I tried to install has screwed it up. Since the last successful use of the usb I tried to install Acronis Drive Image (It did not complete), Serif Movie Maker 4 (it aborted because my processor lacked sse support), Ulead Movie Factory (it did not complete). I've uninstalled these. Subsequent to finding the usb problem I've also used Fix-it utilities to remove 'left-overs' of the above three programs from the registry. Acronis was the most prolific in leaving entries. I don't know if it also related to the fact I can't restore. The restore goes through the motions, restarts and then says it can't restore because there is not enough disk space (200mb) although I have 12Gb free. Can anyone suggest which system files might be missing or corrupt for my usb problem? A search of the Internet has not been fruitful. None of the MS help pages covers the problem because they all assume you get some kind of error message. |

Just a wild guess and based solely on the number of aborted installs you
appear to have suffered. Check your windows\inf folder (a hidden system folder and you will have to enable the viewing of such files and folders in Explorer (Tools | Folder Options | View and check "Show hidden files and folders" and uncheck "Hide protected operating system files") and look for large numbers of oem*.inf files that are all 0 bytes in size. If you've got thousands of such files this could be the cause of your problem. Delete ONLY the 0 byte oem*.inf files. System Resto What is the version of the file smgr.dll in the windows\system folder? You can check this by locating this file in Windows Explorer, selecting, right clicking and choosing Properties and then clicking the Version tab. If not 4.90.0.3003 then that could be the cause of the problem and you need to download and install the 290700 patch for system restore. The easiest way to do this is from the link in the associated KB article (KB290700 - "Checkpoints that you create after September 8, 2001 do not restore your computer" (http://support.microsoft.com?kbid=290700). It is also possible that at one stage you did install this patch but have subsequently reinstalled Win Me over itself using the Win Me CD. Doing this causes the original, broken, version of smgr.dll to be reinstalled. If this problem is a result of your having reinstalled Win Me over itself may I recommend you to download and use the Belarc Advisor (http://www.belarc.com/free_download.html) which will help you in identify which other patches also need to be reinstalled. -- Mike Maltby cut this out" ""lionelcarter\"@(cut this out)lineone.net ""lionelcarter\"@(cut this out)lineone.net" wrote: I've lost my ability to hot swap usb2 devices after using them successfully for several years.

I don't know if it also related to the fact I can't restore. Do you mean System Restore? If so, and you only recently installed Acronis, etc., you *might* be able to get back using scanreg /restore. But that will only offer you the last 5 days worth of registries - let's hope it's in that time frame. Boot with your Windows Startup (floppy) Disk already inserted in the A: drive, and choose option 4) Minimal Boot. At the A:\ prompt, type "scanreg /restore" (no quotes and note the space between the g and /) then press Enter. Follow the screen prompts and when asked, select the LAST 'good' date BEFORE THE PROBLEM, continuing with the instructions. Don't forget to remove the floppy disk BEFORE you tell the machine to reboot. Good luck Mart "cut this out" ""lionelcarter\"@(cut this out)lineone.net" wrote in message ...

Thanks for the advice but to no avail, unfortunately.
There are no 0 byte oem files in INF folder, Just 4, 5 to 7 bytes long. My smgr.dll version is 4.90.0.3003. So far I've never had to use safe mode or the ME cab disk, or System Restore. The pc has behaved itself very well (bought in 2006). I did mean system restore. Unfortunately this happened about 2 weeks back and I've had to carry on using pc so scanreg won't go back that far. My simplistic mind was thinking if I could identify the 4 or 5 system files that relate to usb usage I could recopy them. For example, the one that detects and throws up the disconnect icon when you plug a usb device in Thanks for pointing out Belarc Advisor. I must admit I've don't update all MS patches for ME on the basis of if it's not broke don't fix it. As I said usb and everything else was working fine. I feel one of the instal programs walked all over existing settings/files. |

System Restore.
Reset and test as follows: System | Performance | File System | Troubleshooting and check "Disable System Restore", Apply and IMMEDIATELY reboot. This will flush you restore folder and erase all checkpoints, then, System | Performance | File System | Troubleshooting and uncheck "Disable System Restore", Apply and again IMMEDIATELY reboot. This should now automatically create a new checkpoint immediately following the restart. Finally adjust the space allocated to the restore folder, System | Performance | File System | Hard Disk and adjust the restore slider to your preferred setting. A figure of 2-300MB is normally more than adequate for day to day use allowing perhaps a week of checkpoints to be available although increasing this to perhaps 400-500MB for a few days during periods of large installs such Microsoft Office is advisable. Finally carry out the following quick test to check if all is now in order. a) Create a shortcut on your desktop to a file. b) Create a manual checkpoint Could you create a checkpoint? c) Delete the shortcut d) Restore your PC to the checkpoint you created. Was the shortcut restored? Did you see any error messages? e) Reboot your PC Was the checkpoint retained? -- Mike Maltby cut this out" ""lionelcarter\"@(cut this out)lineone.net ""lionelcarter\"@(cut this out)lineone.net" wrote: Thanks for the advice but to no avail, unfortunately.

... files that relate to usb usage I could
recopy them. For example, the one that detects and throws up the disconnect icon when you plug a usb device in. Probably not the answer. That icon is contained in systray.exe and is used for other devices than just USB, e.g. PCMCIA Cards, Zip Disks, etc., as well as other system tray utilities. I suppose you could also try a scanreg /fix but I suspect that the problem is somewhat more complicated, as Noel and Mike have suggested.

Gentlemen,
Thanks for your help. I've tried to be a bit more explicit below, but don't want to write a book! I would be grateful for any further suggestions. I feel reinstalling ME would be a 'cop out' as I would still not know what went wrong. System Restore I faithfully followed your instructions Mike and it worked OK. There was one hairy moment when Spybot popped up and said it detected a change, should I accept or refuse. But it bombed on while I was reading it so I had not responded. Also I found 4000mb had been allocated to restore! I've brought it down to 637mb. So thanks; my system restore is now operative. INF files We are a bit at cross-purposes here. I have 587 files in my INF folder. None are 0 byte. I looked for oem*.inf files and found: OEMCPL.INF 08/06/2000 OEM0.INF 24/08/2001 oem1.inf 23/10/2003 oem2.inf 05/02/2003 oem3.inf 04/03/2005 oem4.inf 04/03/2005 These all predate the problem by at least a year There are only two files for 2006 (excluding AVG updates) in the INF folder. They are around the time of the problem arising. They are stmanim.inf and mswmp.inf both dated 30/03/2006 and having the same time. They seem to be related to MS Media Player. I've not knowingly altered my MS Media Player. It still works OK. I can only think it decided to link to the Internet of its own accord to update itself or find a codec etc. A bit more on the symptons: If I plug in, say, my external USB hard drive 'hot' and then try to access any folder/shortcut I get a constant hourglass. Using CtrlAltDel I get 'Msgsrv32 not responding'. If I have external drive connected up before I power up the pc then it is recognised and I have the disconnect icon. If I disconnect the external hard drive everything still carries on OK. I can access folders etc as normal. Similarly if I have two external USB devices connected before power up then they are both recognised and work Belarc Advisor Works fine and recognises everything, including external hard drive and USB ports. No problems reported and all 18 MS hot fixes ticked as OK. |
