Hi!
I bought a (cheap) video grabber to convert few remaining VHSs. It's
this (full lsusb -v output at the end):
Bus 003 Device 014: ID 534d:0021 MacroSilicon MS210x Video Grabber
[EasierCAP]
Device Descriptor:
bLength 18
bDescriptorType 1
bcdUSB 2.00
bDeviceClass 239 Miscellaneous Device
bDeviceSubClass 2
bDeviceProtocol 1 Interface Association
bMaxPacketSize0 64
idVendor 0x534d MacroSilicon
idProduct 0x0021 MS210x Video Grabber [EasierCAP]
bcdDevice 1.21
iManufacturer 1 MACROSILICON
iProduct 2 AV TO USB2.0
iSerial 3 20150130
bNumConfigurations 1
But it offers resolutions only up to 720x480. In Windows, I can grab the
standard PAL's 720x576. Is there any way to force the native res in UVC?
Or can you point me the way how to debug/fix this?
Thanks.
Dumps and logs follow.

Three /dev/video devices are created. Two UVCs (3+5) and one real video (4):
