Looping and capturing works without errors.

I'm very pleased, thanks for the good work!

(in dmesg my QHY5 shows up with idVendor=1618, idProduct=0921, that number is not in 85-qhyccd.rules but it still works)

Your camera is in the rules :)

ACTION=="add", SUBSYSTEM=="usb", ATTRS{idVendor}=="1618", RUN+="/bin/sh -c '/bin/echo 256 >/sys/module/usbcore/parameters/usbfs_memory_mb'"


I still have the " GetQHYCCDSingleFrame error (-1)" error with the new 85-qhyccd.rules

I guess it´s the 2xUSB 3.0 ports. Each one must be able to supply 900mA


I had problem with the Canon DSLR driver. Then i used the GPhoto CCD instead. Now it works perfect.
