I have an external USB 2.0 hub that connects to a USB 1.1 slot on my PC running Windows Me. The hub recognizes and allows me to use a 1.0 GB Sandisk USB flash hard drive and another 2.0 GB flash hard drive with no problems, but refuses to work at all with 2 different brands of 12 GB USB flash drives I've tried. (What happens is either that Windows will sometimes detect, other times not, the flash drive, but in either case never completes the process of adding the 12 GB flash drive in the toolbar.) Not sure why it works for some USB flash drives but not for others -- perhaps this means my USH hub is defective?

[Edit to original message: another oddity is that when plugged directly into my other USB 1.1 slot, the 12 GB USB drive works fine -- it's only when it's connected to the USB hub that generates problems.]

Is your Usb hub powered by your computer or is it self powered (I:E, mains).
1. If powered by just your computer, it will
be limited to how many devices you have
connected and the power from your computer
port.
2. If mains powered then you will only be
limited by the number of ports on the hub,
and not be affected by the power loss
(see section (1)).
3. Some Usb devices only work properly on Usb
2 format, so maybe that is why you are
having proplems, is there a way you could
update your Usb ports/hub to USB2 format?.

Does your hub have its own dc power supply?
If not that could be the problem.

Yes the USB hub has its own DC power supply that plugs into an electrical outlet.

Sorry I can't help your USB issue, but It's a miracle you have ME and it's still running. Do you have to restore from image everytime you boot or something? I think the longest I have ever seen ME run without crashing was 6 months. Best of luck.

Actually believe it or not, Windows ME actually runs pretty reliably on my classic PC (this is a PC I use for running older PC games and Roland ISA hardware that are not compatible with modern PCs). In fact, I rarely ever have to reboot the Windows ME PC (maybe once in say 2 months), whereas I have to reboot my modern XP PC at least once a week. The classic PC used to have Windows 95 OSR 2.5 installed before ME, and ME behaves much much better than 95 did.
