RE: USB2 problem

It is strange. I've since had 100% USB2 connections with the Archos
firmware. Interestingly the intermittent reboot problem with this firmware
has now gone since I replaced the batteries with fresh NiMHs.

The same problem persists with the rockbox firmware though. More often than
not I can't connect at all. If I insert the USB plug very very slowly I can
sometimes establish a USB(1) connection without it rebooting.

Mighty weird!!

I thought that usb was entirely handled by the hardware chipset...
