RE: USB slave

There is slave support in hardware but not is software. It is ofcourse
possible
to add such support.

Subject: USB slave


Hi,
our aim is to use an USB port as slave on Etrax 100 LX. I have read 
specifications that explain how to set up this operation mode.
To support usb device mode in Linux (from AXIS SDK) I have unchecked the

USB2 port in USB host support (in the kernel configuration)...this mean 
that USB will operate as slave.

And...some hardware modification: a usb device connector (solded in J4 
of Fox board) and a pullup resistor (1K5) between D+ and Vcc as 
described in:
http://developer.axis.com/doc/hw/etrax100lx/des_ref/20060209/etrax100lx_
08_usb.pdf

So I tried to connect a usb cable between my Etrax 100 LX (Fox board) 
and a Windoze PC, but the devices result unknown with ProductID=0x00 and

VendorID=0x00.

May be I lost some step? Each device must have a ProductID and a 
VendorID, but I haven't found such parameters inside the Linux usb code.

Where is the mistake?

Thanks to all
