why does driver work one week and not the next

Hey Geeks; Man this is getting stupid. Was here about two weeks ago having problems with Prolific 2303 driver. tgell did great job and found me the right driver. Now this week in device manager I have a yellow exclaimation sign saying code 10 and the device I am trying to work wont function. I have updated and uninstall/reinstall. I even downloaded the driver that tgell found again and than installed it. any ideas why driver works one week and not the next. I guess I go looking for different driver huh?I run wins xp on toshiba satellite pro. Thanks in advance for help_____ Techs here are sharp I always get great support here. Luv u guys. Also I have not updated wins since last fix or done anything that should of affected that driver

 

Thanks for answering. Tried installing driver tgell found for me and no did not help. I am running wins xp pack 3. My computer came with vista; has xp now but wins 7 was on my computer at one time. I have a Toshiba Satellite Pro model L300. I have done all the usual things. UNinstall roolback reinstalled update the works.

 

Not sure what is happening. Disconnect the device from the usb port. Download USBDeview and run in an admin account. Delete all vendor specific devices. Reboot and then connect your device.

tgell!! how you doing man? I hope you meant drivers not devices right? I am sending log too. Thanks for help. Also thanks DavidGP for your help. Now I have no more warning sign. You are still the man bro!!! Now what is it that I might be doing to mess things up as it is probally me?

 

Doing okay. When you run USBDeview you should see vendor specific devices. You can safely remove these. Sometimes one driver conflicts with another. These will be reinstalled the next time you connect a USB device. Delete only the Vendor Specific Devices. Have you tried inserting your USB to serial device in a different USB port? Try that first.
