rt73 driver doesn't work in 2.6.24

rt73 driver doesn't work in 2.6.24

[Adam Turk]

Hello,

I was rather pleased to see that my Edimax ew7318usg was supported by mainline.  I created a new config, compiled, (no errors), and rebooted with the wireless card plugged in and I get errors on module load. Here is the output from dmesg:

rt73usb 1-1:1.0: usb_probe_interface
rt73usb 1-1:1.0: usb_probe_interface - got id
phy0 -> rt73usb_validate_eeprom: EEPROM recovery - NIC: 0xffef
phy0 -> rt73usb_validate_eeprom: EEPROM recovery - Led: 0xe000
phy0 -> rt73usb_validate_eeprom: EEPROM recovery - RSSI OFFSET BG: 0x0000
phy0 -> rt2x00_set_chip: Info - Chipset detected - rt: 1300, rf: 0002, rev: 0002573a.
phy0: Selected rate control algorithm 'simple'
phy0: Failed to initialize wep
phy0 -> rt2x00lib_probe_dev: Error - Failed to initialize hw.
rt73usb: probe of 1-1:1.0 failed with error -12
usbcore: registered new interface driver rt73usb

What do I need to do to get a working rt73usb driver?
Thanks,
Adam

This is a problem with mac80211 loading the wep encryption, did you load the arc4 module?

No it doesn't appear so.  So lets do it:
insmod arc4.ko=20
rmmod rt73usb
rmmod rt2x00usb
rmmod rt2x00lib

I then unplugged and plugged in (waiting 30 seconds) and still no joy. =
Same messages as earlier.  Does arc4 have to be compiled into the kerne=
l?

Thanks,

This is a mac80211 bug and not a rt73usb bug.
Apparatently the crypto_alloc_blkcipher("ecb(arc4)") call is failing,
more then that I have no idea what can cause this.
Any mac80211 developer with more information?

I just compiled a new 2.6.24 kernel with arc4 compiled into the kernel =
and still the driver gives the following output:

rt73usb 1-1:1.0: usb_probe_interface
rt73usb 1-1:1.0: usb_probe_interface - got id

phy0 -> rt2x00lib_probe_dev: Error - Failed to initialize hw.
rt73usb: probe of 1-1:1.0 failed with error -12
usbcore: registered new interface driver rt73usb

Despite the statement about registering the new interface driver rt73us=
b, the interface is not created. Can someone please tell me what is wro=
ng and get a fix into 2.6.24.1?

Thanks,
Adam
