I am using the Abocom WUG2690 wireless USB module with Linux with 
the zd1211 driver from the latest

It appears that Abocom is using a mix of ZD1211 and ZD1211B chips without 
assigning a different USB vendor/device-ID. The bulk of devices I see use 
a ZD1211B.

I have changed the "static struct usb_device_id usb_ids[]" table to have 
the correct entry for a ZD1211B like this:

        { USB_DEVICE(0x07b8, 0x6001), .driver_info = DEVICE_ZD1211B },

Unfortunately this means that it will no longer work with a ZD1211 (non-B 

Another problem is that the AL2230S RF chip is not correctly recognised, 
but seen as a "UNKNOWN_A_RF". I tried to work around this by adding the 
type "UNKNOWN_A_RF" to the function zd_rf_init_hw() in file zd_rf.c like 

        case UNKNOWN_A_RF:
        case AL2230_RF:
                r = zd_rf_init_al2230(rf);

This hack makes the driver work, but there is some packet loss. I suspect 
that the RF chip is not setup correctly (for a AL2230S).

Any ideas on how to fix this properly?
