Hi dear usb driver developers!
First of all let me describe my hardware platform and software.
I've got hardware platform based on s3c2410 samsung arm cpu, isp1761 philips
usb hi speed chip, au6368 card reader chip.
I use linux kernel 2.6.19 and pehci usb driver ported to this kernel.
During booting my kernel - during loading pehci.ko driver, sometimes (1 time
of 20) an error appears:
hub 1-1:1.0: 3 ports detected
usb 1-1.1: new high speed USB device using isp1761 and address 3
usb 1-1.1: device descriptor read/64, error -71
usb 1-1.1: device descriptor read/64, error -71
usb 1-1.1: new high speed USB device using isp1761 and address 4
usb 1-1.1: device descriptor read/64, error -71
usb 1-1.1: device descriptor read/64, error -71
usb 1-1.1: new high speed USB device using isp1761 and address 5
usb 1-1.1: device not accepting address 5, error -71
usb 1-1.1: new high speed USB device using isp1761 and address 6
usb 1-1.1: device not accepting address 6, error -71
And after that my card reader doesn't work.
So, my question is, why this error appears and how can i solve it? Did
anybody test usb driver on philips isp1761?
Sincerely,
Max Andruschenko.
