I have tried to use 2 new 2Gb USB Memory sticks in my Mesh desktop PC running XP with SP2 and USB 2.0 interface. Both of these bring up the "found new hardware wizard" in Windows and want a CD with the drivers on. The PC's recovery disk and the XP SP2 disk do not contain what the wizard is looking for.
The CD that came with one of the sticks has drivers for Win98 and use of these brings up the message "XP does not need drivers for this device"
Both sticks work fine in a laptop, also running XP with SP2 but only with USB 1.1 ports so I get a "this device can run faster" message but the drives work fine.
I have a USB 2.0 card reader which works fine when plugged into any of the USB ports on the desktop.
I have tried refreshing the USB stack and various other suggestions I discovered by searching the forum here but without success.
Refresh USB Ports Use Drive clean up to remove USB device drive info from the registry click here or In device manager Uninstall EVERYTHING under the heading USB, reboot the PC let XP find and install new hardware. Your equipment should now be recognised.
USB Permissions Start - Run and type regedit Press OK. Navigate to: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Enum\USB. Right click on the folder and pick permissions. Set to ALLOW. Do the same for: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Enum\USBSTOR
+ Universal Serial Bus Controllers -Standard Enhanced PCI to USB Host Controller -Standard OpenHCD USB Host Controller -Standard OpenHCD USB Host Controller -USB 2.0 Root Hub -USB Printing Support -USB Root Hub -USB Root Hub
All appear to be OK, no yellow question marks anywhere.
The memory sticks work fine on the laptop which is USB1.1
