USB Dongle and Wimax (GCT Semiconductor driver)

[monkeygirl]

Hello, I recently bought wimax service and the USB dongle I received doesn't seem to have a driver. I haven't found any topics online relating to a successful wimax connection in Linux. Before using usb_modeswitch only the 'cdrom' was recognized, but lsusb displayed that the hardware was connected. After usb_modeswitch the following message is displayed per dmesg:

and the lsusb no longer shows a connection:

I have never used wireless with linux, but I used a Huawei/Emobile dongle for a year with no problem. That said, I'm not sure where else to look for answers and having no knowledge of wireless or wimax, I'd really any advice on how to set up my service. Is there a specific driver for the GCT Semiconductor/Wimax Network Adapter? One that madwimax will recognize?

I like the wimax service (it works well on both my mac and winxp laptops), but I primarily use linux and would like my HP-Mini netbook as my main travel laptop.

From what I read after a quick Google, you want to talk to this lot:

Thanks. That was one of the first forums I visited when I queried for help on Scroogle. However, I've browsed that forum extensively and there is no answer. Also the dates from the past threads are 2010 latest. Again, thanks anyway for offering the link.


Update: I unmerged usb_modeswitch and plugged in the dongle again. I got the following error trying to read the device descriptors with lsusb -v -d 1076:7f40
[cut]
Endpoint Descriptor:
bLength 7
bDescriptorType 5
bEndpointAddress 0x04 EP 4 OUT

Device Qualifier (for other device speed):

bDeviceClass 10 CDC Data
bDeviceSubClass 0 Unused
bDeviceProtocol 0
bMaxPacketSize0 64
bNumConfigurations 1
cannot read device status, Broken pipe (32)

After typing the command again, I got the following error:

Endpoint Descriptor:

Wherein the device qualifier is no longer read. I can repeat this error reading, but it is Greek to me. Any wimax know-how feedback would be greatly appreciated.
