Can bad NAND blocks cause USB's "device descriptor read/64, error -110" ?

It was enough today just to flash this:
and cdc_ether immediately gave out usb0 (before to even get the usb `new
full speed USB device using uhci_h....' line, I had to suspend and then
So, it was the kernel's problem (and for some reason the 20080826 did
not work (bad image) on my FR DateCode: 20080725).
Case close, into the new explorations! ;) and thanks for everyone's care,
