I'm trying to get the RSA306B API to communicate using Python on a Linux OS. I keep getting an error when the example program does a search for exiting instruments. The program errors out when reading the the <strong>cyusb.conf</strong> file.&#160;<br> <br> Here is the unedited <strong>cyusb.conf&#160;</strong>file contents:<br> <br> # This is the main configuration file for Cypress USB FX2 and FX3 devices<br> # All lines beginning with a # in the first column is treated as a comment<br> # Blank lines are ignored<br> # Author &#160; &#160;- V.

My issue is the proper formatting.<br> <br> I've tried the following without success:<br> <br> LogFile=/RSA/RSA_API_0_13_220/cyusbd.log<br> PIDFile=/RSA/RSA_API_0_13_220/cyusbd.pid<br> <br> LogFile=&quot;/RSA/RSA_API_0_13_220/cyusbd.log&quot;<br> PIDFile=&quot;/RSA/RSA_API_0_13_220/cyusbd.pid&quot;<br> <br> Has anyone successfully modified the modified the&#160;<strong>cyusb.conf&#160;</strong>file? If so, what is the correct format for specifying the above directories?
