Issue Description

I am having problems with the RealSense D435 camera. It seems that the problem arises from the auto-exposure option. I have written C++ code that can either use the auto-exposure or the manual value. As I had problems running this code (it worked before) I headed to the RealSense Viewer where I found that setting the auto-exposure value is a bar rather than a checkbox:

I cannot change the value of the auto-exposure neither by manually sliding nor entering a value and results in the following error:

Invalid Value in rs2_get_option(options:00000247516A92A0, option:Enable Auto Exposure):
get_xu(id=11) failed! Last Error: No error

Manual change of the exposure value, or, in fact, any parameter, is also not effective.

I have restarted the PC, but did not make any difference. I also had SDK version of 2.19.0, which I removed and installed 2.21.0, but the result was the same. Unfortunately, the PC is in a remote location, so I cannot make any physical changes.

Hard (plug out) reset did not help - it helps to start the RealSense Viewer again, but not none of the parameters can be changed, which results in a "Not responding" software requiring another hard reset. A working solution was reached once:

• The camera firmware was upgraded from 05.11.01.100 to 05.11.06.250 (5.11.4.0 also worked);
• RealSense SDK was upgraded from 2.19 to 2.25 (most likely it was not the reason why it was not working as it worked before);
• Changed the physical USB port (as RealSense Viewer once showed USB 2.0 (there are examples online);
