It's not my original flash, it's not my flash at all and here is the main problem: I haven't any my own working flashes. And what I done: 1. Yes, all of them are OK, e.g. files are readable, writeable and erasable at another computer 2. Working flash is still working 3. I downloaded KB240075, but didn't install it, 'cos those guys say it's for AMD & VIA, not for my Intel. Am I right? 4. I can't access to XP machine, but I have access to another 98SE machine, so I looked into HKLM\Enum\USB section of system registry and found VIDs & PIDs: working Kingston VID 0951 PID 1625 useless Kingston VID 0951 PID 162D useless EMTEC VID 13FE PID 1F00
