We have 100 of these ThinkCentre M52 8215-E7U. Most of them have local HP LaserJet 1020 printers attached. All has been well up until last month... Here’s the issue:
Computer has the printer connected on power on (like always). User inserts a USB Flash drive... now, on most computers it reads the drive with no problem. BUT, have 4 or 5 computers that will recognize the flash drive but cannot read anything on it nor will write anything to it. However, if you remove the flash drive, disconnect the USB printer, and then plug flash drive back in, it’s good to go. I can even re-connect the printer at this point and everything works great up until the computer is rebooted or the flash dive is removed and reinserted. This happens with any flash drive tried.
I’ve tried reinstalling print drivers, USB drivers, host controllers, I’ve even had the motherboard replaced but it still is doing the same thing. I need help to resolve this one!
