em28xx driver is capable of handling more than one usb device. However, isoc transfers require a large amount of data to be transfered. Before this patch, just one em28xx board were enough to allocate more than 50% URBs: T: Bus=02 Lev=00 Prnt=00 Port=00 Cnt=00 Dev#= 1 Spd=480 MxCh= 8 B: Alloc=480/800 us (60%), #Int= 0, #Iso= 2 D: Ver= 2.00 Cls=09(hub ) Sub=00 Prot=01 MxPS=64 #Cfgs= 1 So, only one board could use an USB host at the same time. After the patch, it is possible to use more than one em28xx at the same time, on the same usb host, if the image size is slower or equal to 345600, since those images will require about 30% of the URBs: T: Bus=02 Lev=00 Prnt=00 Port=00 Cnt=00 Dev#= 1 Spd=480 MxCh= 8 B: Alloc=232/800 us (29%), #Int= 0, #Iso= 2 D: Ver= 2.00 Cls=09(hub ) Sub=00 Prot=01 MxPS=64 #Cfgs= 1 So, in thesis, after the patch, it would be possible to use up to 3 boards by each usb host, if the devices are generating small images.

videobuf functions at close() method already locks videobuf. It makes no sense to keep the locking at empress close() method. There is also a lock at open() method. I'm not sure if it is safe to remove the locking there. Signed-off-by: -

I updated the radio-si470x driver another time. Here are the commented history entries: - number of seek_retries changed to tune_timeout The last versions checked for the end of frequency tuning by polling a si470x register. Therefore polling depended on the usb utilization. This was changed to have a constant timeout now. - fixed problem with incomplete tune operations by own buffers The last version used a shared buffer to assembly the USB HID reports. It sometimes happened, that multiple functions were modifing this buffer simultanuously. When sending such reports, the hardware returned USB stalls (-EPIPE). Now buffers of the correct size (smaller than before) are allocated as local variables. - optimization of variables The size of some variables has been reduced to allow the compiler to generate more optimized code. - improved error logging At some important location, error checking was improved. Especially the usb transfers to access si470x registers and the tuning functions were modified. Signed-off-by:
