USB device not accepting new address=2 (error=-19)

USB device not accepting new address=2 (error=-19)

[ckbb ckbb]

I am stuck with the following error. I really appreciate any help for this 
problem. May be it is known bug in the usb stack.

I am using linux2.4.21, powerpc processor, phillips 1161a host controller

I am getting interrupts & hardware seems to be OK. I have configured EHCI & 
OHCI, scsi, usb mass storage in the kernel configuration.

Looks like a pci interrupt routing issue.  Is the usb host controller
actually getting interrupts?

Is this a custom motherboard, or is it a Apple machine?

Odds are it's a bug in the hcd_1161 driver as almost no one uses that
driver and I doubt it is up to date.

thanks,

yes it is coustomised board and ISP1161A host controller is connected to a 
fpga device which is on the PCI bus. Infact it is one of the general purpose 
io (gpio-23) to which usb interrupt line is connected and gpio is programmed 
as an interrupt. I am getting the 'sof' interrupt continuously (at every 
1msec) and I can see the corresponding interrupt count in /proc/interrupts 
is incrementing accordingly.

Regarding hc 1161a, I have been told by phillips factory people that the 
driver is working fine with the x86 platform. I did a port to the powerpc 
platform.

Then I would suggest looking at that driver, for that is where the data
comes back from the usb device to.  And it looks like no data is being
received properly.

Good luck,
