usb on mpc823 in slave mode ..?

Hello ,

I am putting efforts to initialise USB in slave mode on
mpc823.
when i connect to my pc i get messages like

usb-uhci.c: interrupt, status 2, frame# 1748
usb.c: USB device not accepting new address=19 (error=-110)

this makes me to doubt usb controller's interrupt at mpc823 is not
being requested, assuming onther intialisations are o.k.

I am using CPMVEC_SCC1  for my usb interupt that has been
defined as 0x1e..

also when I try to read pending interrupts from interrupt
controller( from usb controller routines) it always shows the 18th
bit in sipend register as pending.

i.e. o/p of
printk("pendinginterrupts is
0x%x\n",((immap_t*)IMAP_ADDR)->im_siu_conf.sc_sipend);

is 0x20000 , which is IRQ 3 as per manual.

any idea on this...

Best Regards,
