Hi all,
I have the isp116x-hcd driver running on my ixp425 platform under kernel
2.6.14. The driver seems to be loading and initializing the USB HC
device properly. However as soon as a plug a mouse or any other similar
device i get " device descriptor read/64, error -32 " followed by "
device not accepting address 4, error -32" as i have enabled both old
and new device initialization schemes (hub.c:77 static int
use_both_schemes = 1; ).
The following is the output that i get after a device is plugged (i have
added indication of what interrupts are pending + PTD trace output) :
Irq: HCuPINT_SOF
Irq: HCINT_RHSC
Irq: HCuPINT_SOF

I am using ndelay currently hardcodded for 350 ns.
Any visible problems form what i have pasted (i dont quite understand
PTD yet) that could be causing the device attachment failures?
