Re: Re: [linux-usb-devel] about usb device on PXA255
Hi,Robert Schwebel You have to write a gadget driver: use the pxa2xx_udc controller driver (which talks to the hardware and handles all the hardware access stuff), drivers/arch/mach-pxa/usb_ctl.c -/usb_ep0.c -/usb_recv.c -/usb_send.c Do you mean these files acting as the pxa2xx_udc controller driver? I have build the driver as modules and loaded it.when I connet the HPC to the PC(windows system),what should be happend? Should the PC recognize the HPC as a USB device? When I have done these ,nothing occured. on top of that you should write something that implements the specification for storage devices. Look at the existing gadget drivers (gadget_ether, gadget_zero) to see how things work...

[linux-usb-devel] about usb device on PXA255
Hi,all I am a newbie on usb device.Now I have a task about the usb device on PXA255.we have designed a HPC which based on PXA255 and we want to use the HPC as a mass storage device(a usb removable disk) through the usb on pxa255. Would you like to tell me how I can get a start and introduce me the steps to work? Are there have some reference? Thanks a lot.
