Agilent U2761A Support

[codyneslen]

Thanks so much for this module! Super helpful.

I'm trying to enable access to the U2761A from Agilent (Keysight). I see your code sending over commands to switch the other U27* devices from firmware mode to usbtmc. I've tried adding the idProduct (0x3B18 -> 0x3C18) for the U2761A and can successfully see the device, but when I try to open the instrument, I cannot switch it from firmware mode. I'm assuming I am not sending the correct info to switch it over (there's 1 wIndex different between your U2701A and U2772A devices). Do you know the correct data to send for the U2761A, or know how I can figure it out?

Hi
Did you manage to find the correct sequence?

The only way I could use the instrument with Linux was:

• connect it to the Windows machine first
• run Keysight connection expert
• disconnect the device from the Windows machine and connect it to the Linux machine without switching power off
