I'm afraid there's no USB support at present. Sometimes it's
possible to configure the BIOS to emulate PS2 mice and keyboards.
Alternatively, many USB mice come with a USB -> PS2 adaptor.

Under the new IO model adding USB support will be rather easier.

USB drivers

[Cong Du]

Hello,
          Does Xen support usb device?
          I am using a usb mouse, but I can not build the usb driver modules in xenolinux-2.4.26/drivers/usb.
There are no config options for it. and "ARCH=xeno make" does not work.

Best regards.

USB drivers

[Ron Madrid]

I have a custom board based on the MPC8313ERDB and have communications
capabilities over Ethernet using internet sockets.  Basically, just data
transfer from the host (my board) to a client (a PC).  I want to be able to
perform similar transactions across USB.

I have done some cursory reading but am a little unclear on how I should
approach this.  Am I going to have to write a host driver for my custom
board, and also write a gadget driver for any client machine?  Also, since I
am desiring to do simple data transfers only, which drivers could I use as a
point of reference for my application?

Thanks in advance for any tips and suggestions.

Ron

Linux has a g_ether gadget, which can simulate a ethernet tunnal over
USB.  If you already have the communication code through ethernet, it
will be easier to make use of that gadget.  However, it has more
overhead than pure usb transactions.  The best way is like you said,
custom gadget driver and host driver.

Hi,

? Iam new to this ML,I need info regarding Usb device drivers.I had learned Lnx device drivers and having
?knowledge on USB Host driver(highlevel).

? I had seen probe/read/write functions of a driver.As there is no need to write drivers from scratch,we can gain knowledge by fixing some bugs in the driver.

Can some one please give me links/doc to see the bugs and related fixes of USB drivers.

BR.

Hi Kalyan,

Can you start reading the USB driver development from the following link?
Apart from this, you can develop a skeleton USB driver and even you can
develop a GADGET USB driver.

Regards,
Srinivas.

Hello Kalyan,

I would suggest you to have a Look into Linux Device Driver Book by
Alessandro Rubini & Jonathan Corbet and before that you should understand
the USB Stack Linux architecture .

Sanjeev Sharma
