OK, we need to find out how many endpoints your device has.

1. # usbconfig -u 0 -a 2 -i 0 dump_all_config_desc

And post the result of the command here please.

Aha, as i thought, your device has 5 endpoints but my rt2870 chip has 7 endpoints. I need to investigate that.

I will give you a feedback later when i'm done.

Did you try if_run driver ? You can find it in another forum here.

My device has 7 endpoints: 1 Rx queue and 6 Tx queue (4 EDCA + MGMT + HCCA). Your device has 5 endpoints: 1 Rx queue and
4 Tx queues (4 EDCA). Your device doesn't have MGMT and HCCA Tx queues but it is not a problem because HCCA queue is never used and MGMT queue can be replaced by one of the EDCA Tx queues. The Linux driver does this in that way

Wait a minute and i'm going to update the driver.

egorenar · Jan 24, 2010

OK, i fixed the driver rt2870 (FreeBSD 8) so that it should not have any problems with devices that have only 5 USB endpoints. Please test it.

Everything is OK, it's only debug messages, the driver is loaded.
WLAN works on FreeBSD 8 a bit different then on FreeBSD 7.
You need to create a wlan device:

# ifconfig wlan0 create wlandev rt28700 wlanmode sta up

And you also have to configure wpa_supplicant if you want to use security in your WLAN.

And don't worry i'm going to modify the rt2870 driver for FreeBSD 7.2 next week so that it will support your device.
That is if i have time because Mass Effect 2 is coming next week

Unfortunately, I cannot test your device by myself but if you are willing we can do it together.
First, it would be good if you could add debugger support to your kernel and recompile it. With debugger it is easier to find problems because the message you posted doesn't say anything to me :e

OK, already fixed the problem and teste it. It works for me with only 5 endpoints. Download the driver again.

OK, if you have other questions or problems just send them to my ICQ account.
