Hi,
I'm sending firmware to usb device with this code: But it`s falling because the request firmware call didn't put my firmware in a DMA capable area. That's my guess.
So how to request firmware in DMA capable area?
kmalloc your buffer used for USB transfers. Do you have a pointer to your driver anywhere? The code you show below isn't in any kernel source that I can see. thanks, greg k-h
