USB Gadget driver for USB screen?

Does anyone know of a USB Gadget kernel driver for a USB screen? So I can have a linux USB gadget emulate as a USB screen to the host PC, and aquire it's picture as a picture stream? I looked in the gadget documentation and found a "video" device, but apparently this emulates a web camera to the

Hi Doug, John and linux-usb. I'd like to report a regression in commit 3bc04e28a030 (usb: dwc2: host: Get aligned DMA in a more supported way) Apparently the patch does something nasty that the Lantiq platform really does not like as whenever I plug my usb 3g modem into the usb port of my BT

[PATCH] USB: gadget: Document that certain ep operations can be called in interrupt context

This documentation patch specifies that certain USB gadget endpoint operations may be called in interrupt context: usb_ep_queue, usb_ep_dequeue, usb_ep_set_halt, usb_ep_clear_halt, usb_ep_set_wedge, usb_ep_fifo_status, and usb_ep_fifo_flush; while others must be called in

Re: [PATCH 1/2 ] cdc_ncm: Handle multicast Ethernet traffic

Some CDC_NCM devices are used as docks for laptops. In this case, it makes sense to accept multicast Ethernet traffic, as these devices can reside in a proper LAN. Without this, mDNS or IPv6 simply do not work. Signed-off-by: Miguel Rodríguez Pérez --- drivers/net/usb/cdc_ncm.c | 28

[PATCH 0/2 ] cdc_ncm: Handle multicast Ethernet traffic

Dell D6000 dock (and I guess other docks too) exposes a CDC_NCM device for Ethernet traffic. However, multicast Ethernet traffic is not processed making IPv6 not functional. Other services, like mDNS used for LAN service discovery are also hindered. The actual reason is that CDC_NCM driver was
