Hi guys,

Not sure if is the right place to ask since this device use a gspca driver
and not sure if that driver is related to uvc or not, if not please point
me to the right place...

Recently I'm trying to make work a Sunplus crappy mini HD USB camera, lsusb
list this info related to the device:

Picture Transfer Protocol (PIMA 15470)
Bus 001 Device 015: ID 04fc:1528 Sunplus Technology Co., Ltd

  idVendor           0x04fc Sunplus Technology Co., Ltd
   idProduct          0x1528
   bcdDevice            1.00
   iManufacturer           1 Sunplus Co Ltd
   iProduct                2 General Image Devic
   iSerial                 0
...

Using the gspca-2.13.6 on my Fed12 (2.6.31.6-166.fc12.i686.PAE kernel), the
device is listed as /dev/video1 and no error doing a dmesg...but trying to
make it work, let say with xawtv, I get:

This is xawtv-3.95, running on Linux/i686 (2.6.31.6-166.fc12.i686.PAE)
xinerama 0: 1600x900+0+0

libv4l2: error turning on stream: Timer expired

v4l2: oops: select timeout

..or doing:
xawtv -c /dev/video1 -nodga -novm -norandr -noxv -noxv-video

I get:
ioctl: VIDIOC_STREAMON(int=1): Timer expired
ioctl: VIDIOC_S_STD(std=0x0 []): Invalid argument
v4l2: oops: select timeout
libv4l2: error turning on stream: Timer expired
libv4l2: error reading: Invalid argument


vlc, cheese, etc give me similar "Timeout" related messages...

I read some post about similar devices (but ID 12 or 14) that successfully
works with gspca, so it seems that this one is close to work but may be need
a fix on some timeout or something similar on the driver...

Any clue of what can be done?..any suggestions or right place to ask?, do
you need any other info to help to dig into the problem?

Thanks a lot.

Mauricio
