Hi SeokHoMoon,

First, please use copy and paste to put the errors in your e-mail, not screen captures.

> I try to use the latest version of asyn but some error occured. I think there is some compatibility issue in my environment so I used the 4-26 version.

Please send the exact error message when you use the new version of asyn.

What version of libusb are you using?

Mark

First of all, I'm sorry that sending the reply with different email address.
There is some issue at my university mail system so I send the mail with gmail.

Thanks for your support, Mark Rivers and Eric Norum. However, I faced some other issue with usbtmc.
After I saw the Eric's fixed code. I change the drcAsynUSBTMC.c  file like Eric but I saw the new message like below
The version of asyn and base is 4-26, 3.14.12.5 which is same with past.
I try to use the latest version of asyn but some error occured. I think there is some compatibility issue in my environment so I used the 4-26 version.
But when I check the drcAsynUSBTMC.c file of asyn-4.26 and latest version, there was no difference so I think it is not a problem.

  1.  Centos 7 environment (libusb_ver=0.1.4)

  1.  Rasberrypi3 environment (libusb_ver=1.0)

In different environment, the epics shows the same message.
To check the usb cable and the dg812 equipment, I communicate with dg812 by using Ultra Sigma(Program of RIGOL) and Ni-Max test panel but there were no error.

Best Regards

SeokHoMoon
