for the USB byte order problem with the HCF USB driver, a new 
experimental patch named 'hcfusb-1.06-USB_byteorder.patch' is now 
available at:


In order to find the remaining problem with the driver, we will need 
more information. Please send at support at linuxant.com the output of 
'dumpdiag'. Type the following in a root shell:

hcfusbconfig --dumpdiag

Just send us the generated file located in /tmp ('hcfdiag.txt').
