    Device count limit for EzUsb enumeration with CyUSB.sys

    mike.spataro

      Hi,

         

      Is there a limit to the number of devices which can be enumerated with CyUSB.sys?

         

      My current setup is to have up to 18 EzUSB AN2131 devices connected to an XP or Win2003 machine using ezusb.sys.

         

      I have rebuilt the driver to allow more than the original maximum of 8 devices to enumerate.

         

      I wish to move to Windows 7 64 bit, thus I need to use CyUSB.sys, but I wish to know what the device limit is before I put the effort into redeveloping the software. If the limit is 8, and cannot be changed, I may have to stick with the 32 bit OS.

         

      Thanks a lot.
