I am trying to add a usb wifi dongle. It uses the rt2800usb driver and has the ralink 5370 chipset. From what I gathered from these forums and google is that the openwrt trunk kmod-2800-usb drivers are not working. I am getting a whole list of errors in dmesg like this one:

rt2800usb: Unknown symbol rt2x00mac_sw_scan_complete (err 0)

Is there something I am missing or that I need to do to fix this?

thanks

I'm using rt2800usb with a Sparclan Ralink dual band wifi usb dongle and it's working great--very fast and stable 11gn wireless connections (still flaky on 11an). I simply selected the rt2800usb driver in the Kernel Module/Wireless section of menuconfig. I'm running OpenWrt trunk.

Thanks. I know I have something to look forward to... I meant to know if opkg install kmod-rt2800-usb would work.

I did try compiling it into the kernel but something was wrong (not sure where/what) that was having trouble with finding a magic bit in some part of the boot process. I did start from scratch and I don't know why but it bricked the router (even no failsafe) I need to connect the serial cable too see whats happening there. (I think I used the wrong fw by accident -- it happens)

Anyways I am happy to know that it works at least if compiled in. I am also running trunk.

thanks.

-edit-
I know the problem. It is the same error as before but like the genius I am I did not test it first on the router with the serial cable connected. now I need to solder on some connection to tftp boot a working fw.

just for curiosity sake here is whats happening. I have no clue why. as far as I know it is a clean build. I have a seperate build where I change makefiles etc.. so it is more likely a mistake from there, but here should be clean.
jffs2_scan_eraseblock(): Magic bitmask 0x1985 not found at 0x00105024: 0x1513 instead

-- thanks again

I tried again from scratch compiled build 29570 with the profile of my router (tplink mr3220) and added only kmod-rt2800-usb into the firmware.

It runs fine but I still dont see how to get it to recognise the wifi dongle. In /etc/config/wireless there is only one radio device. I even had the dongle plugged in on the first boot when it sets up the router. how do I see if its recognising/installing?

I should add that the device I have uses the ralink 5370 chipset.

Run dmesg and post its output and we'll see if we can see what's going on with the driver.

Your dmesg does contain:

Which is very similar to my dmesg:

I don't know why your Ralink radio isn't coming online like mine:

I assume the rt2800 driver is not compatible with your Ralink 5370 chipset.

(Last edited by robrob on 22 Dec 2011, 16:18)

the rt2800usb driver on ubuntu does recognize the device, but I guess I need to focus on the driver not wrt.

Does this site http://cateee.net/lkddb/web-lkddb/RT2800USB.html help me?

--thanks

(Last edited by firesam on 22 Dec 2011, 19:14)

That site indicates the driver supports RT2770, RT2870 & RT3070, RT3071 & RT3072

Your Ralink USB dongle has a Ralink 5370 chipset but it is strange that the Ubuntu rt2800usb driver works.

Do you have these packages installed:

kmod-rt2800-lib
kmod-rt2800-usb
kmod-rt2x00-lib
kmod-rt2x00-usb

Here's my router's lsusb output:

Bus 001 Device 005: ID 148f:3572 Ralink Technology, Corp. RT3572 Wireless Adapter

RT3572 is an RT3072 with 5GHz dual band added (5GHz is flaky on OpenWrt). It's basically a combo RT2770 11gn & RT2750 11an radio.

(Last edited by robrob on 22 Dec 2011, 23:16)

I might be wrong but isn't the 5370 listed in the hardware list on that site?

here is my output:

It looks right to me too.

What about that? Am I making a mistake?
In the section:

Hardware
USB
Numeric ID (from LKDDb) and names (from usb.ids) of recognized devices:
...
vendor: 148f ("Ralink Technology, Corp."), product: 5370 ("RT5370 Wireless Adapter")

-- thanks

also what about this: http://patchwork.ozo.com/patch/838/

as per mailing list openwrt-devel@lists.openwrt.org:

Unfortunately I cannot test it because installing the drivers in windows messed up the dongle somehow. it won't even be recognized in windows and gives error 71 from now on in ubuntu and openwrt. I am getting a new one and will test it when it arrives.
