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.
