Greetings, everyone.
Here's the problem:
I'm working on getting the USB port of a MPC5200B to work, in order to connect this Wireless USB Adapter I want to use.
The
board's been booted with a 2.6.24 linux kernel using U-Boot, (from
DENX) and features the following configurations regarding USB support:
--- USB support
Support for Host-side USB
[*] USB verbose debug messages
*** Miscellaneous USB options ***
[ ] USB device filesystem
[*] USB device class-devices (DEPRECATED)
[ ] Dynamic USB minor allocation (EXPERIMENTAL)
[ ] USB selective suspend/resume and wakeup (EXPERIMENTAL)
[ ] USB device persistence during system suspend (DANGEROUS)
*** USB Host Controller Drivers ***
<> EHCI HCD (USB 2.0) support
<> ISP116X HCD support
OHCI HCD support
[*] OHCI support for on-chip PPC USB controller
[*] OHCI support for PPC USB controller on OF platform bus
[*] Support big endian HC
[ ] ; Support little endian HC
[*] OHCI support for PCI-bus USB controllers
<> UHCI HCD (most Intel and VIA) support
<> SL811HS HCD support
<> R8A66597 HCD support
*** USB Device Class drivers ***
<> USB Modem (CDC ACM) support
<> USB Printer support
*** NOTE: USB_STORAGE enables SCSI, and 'SCSI disk support' ***
*** may also be needed; see USB_STORAGE Help for more information ***
USB Mass Storage support
[*] USB Mass Storage verbose debug
[ ] Datafab Compact Flash Reader support (EXPERIMENTAL)
[ ] Freecom USB/ATAPI Bridge support
[ ] ISD-200 USB/ATA Bridge support
[ ] Microtech/ZiO! CompactFlash/SmartMedia support
[ ] USBAT/USBAT02-based storage support (EXPERIMENTAL)
....
Statically compiled.
I've
also compiled the Wireless USB Adapter driver and its firmware (as a
module) I want to use. It's a RT73(RT2571W) Wireless Lan Linux Driver
for the Ralink RT73 a/b/g WLAN Card.
It had to be done
that way because the 2.6.24 kernel doesn't offer support for this
RAlink driver. I know later versions do, but due to project related
constraints I'm bound to the 2.6.24 kernel.
As I boot the kernel these messages show up (the ones related to USB):

This -62 error is related to request timeout, as Alan Stern has pointed out.
I've tried an USB Storage unit and Dmesg shows:

The device was plugged the whole time, I didn't remove it.
I don't know why it disassociates like that.
Thank you for your cooperation!
