I have a similar configuration but not identical. The checks should run fine on Raspbian.

My Configuration (remote server)
QHY5L-II-M
Raspberry Pi 3
Powered Hub
Ubuntu 18.04.2 LTS
indi-qhy/bionic 2.4~201906051400~ubuntu18.04.1 armhf [upgradable from: 2.4~201906030127~ubuntu18.04.1]
indi-qhy-dbg/bionic 2.4~201906051400~ubuntu18.04.1 armhf

On the desktop side, I am running
kstars-bleeding/xenial,now 6:3.2.3+201905220414~ubuntu16.04.1 amd64 [installed]

After camera is plugged in, verify that the LED in back of the camera is lite. If this fails to light, it indicates issues with the camera. Then in a terminal session, type the following command:
lsusb

You should see:
Bus 001 Device 007: ID 1618:0921

The ID is the important part. Now remove the the camera's usb connection and re-run the command "lsusb", the device should now be gone from the list of the devices. If the device fails to show up , verify the usb cabling.

If the device is present, you can dig a little further by using the command:
sudo lsusb -v | grep -A78 1618:0921

You should see the verbose output now. Here is what my output looks like for comparison:
sudo lsusb -v | grep -A78 1618:0921

Review the output from the following command:
dmesg

You should something like:
[ 2028.646670] usb 1-1.5.3: New USB device found, idVendor=1618, idProduct=0921
[ 2028.646682] usb 1-1.5.3: New USB device strings: Mfr=1, Product=2, SerialNumber=0
[ 2028.646692] usb 1-1.5.3: Product: QHY5-II
[ 2028.646702] usb 1-1.5.3: Manufacturer: QHY-CCD

If you get nothing, test with minimal USB cable length to the camera, replace the USB cable, and check the Pi's Power Supply. You should have at least a 2.5 amp good quality power supply. Also, if you are using a powered hub, I would test with a different power hub. You can test without a powered USB hub, but based on knowing the Raspberry Pi's, I would not recommend directly connecting to the Pi for normal use.

I hope this helps. As stated earlier in this thread, the older QHY5 camera have issues. And the above only pertains to QHY5L-II-M.

Cheers,

Chris
