One way to do it is to use NET2280 card. This has a B
type connector. Check the usb-gadget driver

Did you change the permission for your device?
I think if you try as root you should be ok. Or else
you need to change permission to read and write.

Hi
I'm using 2.4.18-3 (Redhat 7.3) . I have a USB 2.0
device which does DMA read and write. My problem is my
dma usb read is very very slow. Is it because my
kernel doesn't support bulk queuing for read?
My DMA USB write takes 20ms whereas read takes 350ms.
Any help will be appreciated
Hi
I tried compiling usb-skelton.c in 2.5 kernel and
its giving compilation errors. I tried on 2.5.35 and
2.5.40.
Is there anything I need to setup before I will get
this compiled?
Some of the errors on 2.5.35 are
gcc -DMODULE -D__KERNEL__
-I/usr/src/linux-2.5.35/include -O2 -Wall -c -o

Hi,
I'm in the process of understanding the CDCEther

1) Does kernel invoke this callback function
I have a USB device doing DMA.I'm using bulk read and

Can I create the urb-transfer_buffer to 200k and put

Please help me to find some usb debuggers like usb

Use usb-skelton.c, It's there in your kernel source
code.

Hi
I'm writing a driver based on usb-skelton.c.This is
my problem
I need to read/write chunks of data, but in the
skel_write() function(usb-skelton.c) the maximum data
I can read/write is 512.What is teh best way to add
this feature?
1. split data as 512 chunks inside this function and
I'm trying to write using BULK OUT and read using BULK
IN. If I try this in a loop I get device or resource
busy error.
If I use an array of write and read urb structures and
use the urb which is !EINPROGRESS , Will that resolve
my issue?
What is the best way to get around this?
Thanks

I have these modules in

That seems unlikely.
Perhaps you meant uhci-hcd or usb-uhci-hcd?
Show me
modprobe is looking at a
different place. how can I amke the mod probe to see
these modules.
