Jetson nano - slow USB (with libgphoto2 at least)

Hello, not sure if this is the proper forum. I am a newbie here.

I am experimenting with a jetson nano as a robot controller. My robot is normally controlled with a regular PC and it would be interesting to control it with a much smaller and cheaper device.
I have a Sony A5100 camera connected via USB, and am controlling this camera with libgphoto2. It does work, in principle, but the download speed of preview and full resolution photos is low. On the PC i could get about 25 previews a second (the upper limit of the camera i think), on the nano only about 2. The previews are small (1024x680) .jpg files, on average 75KB large. I would expect to see a higher throughput!

Duplicated with USB speed is unexpectedly slow on jetson nano
