Subject: Thorlabs USB Hardare with EPICS

Dear all,

 

I have some problems to establish a longer lasting connection with a Thorlabs PM100USB Powermeter.

 

It is listed in /dev as usbtmc0 and I can communicate with it through echo –e. But this is only possible for one time. A second time echo –e won’t work. I have to disconnect and reconnect the USB-cable. Then again it will work one time.

Could you help me with this problem?

 

Note: This device has two chips, the first one is a XILINX XCR3064XL (AD Converter) and the second a NXP LPC2387FBD100.

 

Best regards,

Hardy Drube
