Hi folks,

My system information Redhat 7.1 and kernel 2.4.9-6.

I have a USB Bluetooth chip, Transilica Evaluation Kit
http://www.transilica.com/prod.html   , the smallest
Bluetooth SOC( system on chip) product. The device is working fine in the
Windows environment and
standalone. We could not even able to initialize the device.  I suspect its
class/subclass/protocol numbers might differ from the "usual" ones
(0xe0/0x01/0x01).  I have tried out to include the usbfs into the
kernel and enabled experimental USB device filesystem  support in the kernel
and mount it as follows:

 mount -t usbdevfs none /proc/bus/usb

but I found that the Transilica device uses the "normal number". The
traces are shown here:

#After USB is plugged into the the Transilica Evaluation Kit 1700 or 1760

#The following messages are recorded in the /proc/bus/USB/devices

Here are my questions:

Could anyone please tell me what  Error (-100) is? It seems that the
transilica bluetooth kit is not supported by the Linux USB (either uhci,
usb-uhci and usb-ohci, also bluetooth.o) driver.

If anyone want to help me include this device into the Linux usb driver,
what are the information I need to provide?

I guess it has nothing to do with the blutooth in this stage,right?

If I want to customize the USB driver include in the kernel to include my
driver, where should I look into?

Thanks.
Best regards,
Xiaoyong
