Re: Fwd: Fwd: request some hep for usb comminucation
Hi Thank you very much for the attention and support. Unfortunately I made a mistake, when I send data to the device, I expected that the device will send an answer for me, while I should read the response from the device. Thanks a lot M.Razavi 2013/6/11 Greg KH gre...@linuxfoundation.org: On Tue, Jun 11, 2013 at 12:29:19PM +0430, Mahdi Razavi wrote: Hi i install windowx XP and Ubuntu in vmware and install a USBlizer (trial) in host windows (win 7 64 bit). next snooping a message between an application and device. and send a same data from ubuntu to device. but device dosent responce.

What device is this exactly? What is the output of 'lsusb -v' with it plugged in? i have a SDK for windows and protocol specification of this device and do some sniffing USB port on connection in windows. may you help me how to have connection with this device in Linux? or how can i write a driver for this device in Linux? What type of interface to userspace do you need for this device? Can it be a dumb serial-like interface that you send it AT modem commands? Or do you need to do other stuff with it? What about just using libusb to talk directly to it from your program from userspace, no kernel driver is needed for that. thanks, greg k-h -- Best Regards M.Razavi -- To unsubscribe from this list: send the line unsubscribe linux-usb in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
