Hello,
When trying to use Agilent U2722A SMU (it has USB interface only) in Windows 7 it is not recognised by NI-VISA as USBTMC instrument. Interestlngly, other instruments like Agilent 33522B and Tektronix MDO3024 work fine and are recognised as USB T&M device (IVI). U2722A remains as "other devices", and when I force it to use the USBTMC driver Windows complains that the driver may not be compatible, and eventually does not show up in NI-MAX and doesn't work.
If I install the Agilent software (their VISA, IO library etc. on a PC without LabVIEW) U2722A works, but this does not agree when LabVIEW is installed. Both NI-VISA and Agilent VISA use the driver ausbtmc.sys.
Has anybody seen this problem? I know of the LabVIEW U2722A driver which uses VISA, so at least one person must have had a success! Please help.
Thanks,
Konstantin
