I'm seeing the same thing (with 4.0_BETA, (not beta2, not had a chance to
upgrade yet)).

The same hardware works with win2k and different flash drives in different
sockets with different cables/hubs makes no difference.

I sometimes can coax umass Bulk transfer stalled messages or something like
that out of it, but i didn't take notes, i thought it was a hardware problem
(i've had problems in the past mixing usb 1.0 and 2.0 devices on an
unpowered usb2.0 hub that claims to be powered when it isn't).

The motherboard is an ASUS A7N8X Deluxe, (single cpu).

I'll try with a 4.0BETA_2 kernel when i've persuaded it to build.
