The slow shutter of the OMC was not opening. There was an error message from the SDB1_Rot process

2025-04-23-19h32m26-UTC>WARNING-error while moving to limit channel 2 axis 1 mode 3

Running the commands by hand did not work either, and after starting the process it didn't not want to restart.

On the computer it is connected to, phasecam1, the device shows on lsusb -v with the following error:

Bus 003 Device 024: ID 104d:3000 Newport Corporation 
Couldn't open device, some information will be missing

The other driver connected to the same computer (the other device is used for squeezing), doesn't not show this error.

Disconnecting and reconnecting the USB cable of the Agilis driver (AG-UC8) did not solve the issue. Disconnecting and connecting the USB bridge it is connected to did not solve the issue. Plugging a spare AG-UC8 did not solve the issue. None of the USB cables connected to phasecam1 looked loose when touching.

To be done is to replace the USB bridge by a spare, and try other ways of understanding why the USB communication doesn't work properly. The device does disappear from the lsusb list when disconnected, and reappears after connecting.
