usb disconnects.

Is anyone having trouble with random USB disconnects when letting the board
run all the time?
Or is it just my kernel or board or usb hub or devices?
It happens every few hours, but I've been unable to time it exactly.... I'm
starting a log on the terminal now.

Hi,

what kernel are you using? I had the same problems with kernel v2.6.26
from Open Embedded and got them resolved by using kernel:

uImage-2.6.26+2.6.27-
rc7+r10+gite1c49d7d22af768188e2a54c167ed79919361e55-r10-
beagleboard.bin

from http://ewi546.ewi.utwente.nl/~koen/

yes, my kernel was built with the kernel that angstrom/openembedded has by default.

After re-compiling with linux-omap instead of linux-omap2, usb disconnects disappeared.
