Hi,

I have downloaded and installed the current project from the git
repos, and insmod'ed the module;
[r...@localhost microdia]# lsmod
Module                  Size  Used by
sn9c20x                69408  0
compat_ioctl32         16512  1 sn9c20x
videodev               40704  2 sn9c20x,compat_ioctl32

dmesg shows the device;
usb 1-1: new high speed USB device using ehci_hcd and address 9
usb 1-1: configuration #1 chosen from 1 choice
sn9c20x: SN9C20X USB 2.0 Webcam - 0C45:6270 plugged-in.
sn9c20x: I2C slave 0x5d returned error during write to address 0xff
sn9c20x: Detected MT9V111 Sensor.
sn9c20x: Webcam device 0C45:6270 is now controlling video device /dev/
video0
sn9c20x: Using yuv420 output format
usb 1-1: New USB device found, idVendor=0c45, idProduct=6270
usb 1-1: New USB device strings: Mfr=0, Product=1, SerialNumber=0
usb 1-1: Product: USB20 Camera


output from lsusb is as follows;
Bus 001 Device 002: ID 0c45:6270 Microdia PC Camera (SN9C201 + MI0360/
MT9V011 or MI0360SOC/MT9V111) U-CAM PC Camera NE878, Whitcom
WHC017, ...

However when I try to use a gstreamer type tool, I get errors in the
dmesg and no output to the application;
sn9c20x: Using yuv420 output format
sn9c20x: Iso frame 0 of USB has error -18
sn9c20x: Iso frame 1 of USB has error -18

sn9c20x: Iso frame 1 of USB has error -18

sn9c20x: Iso frame 3 of USB has error -18
sn9c20x: Iso frame 4 of USB has error -18
sn9c20x: Iso frame 5 of USB has error -18

any ideas?

Thanks,

Tom
