Something curious is happening with my USB HID device.
It is a Full-speed Device. The curious thing is that my VB software transfers 64 bytes of data (EP0 CONTROL TRANSFER) to the device only one time each 05 SOF signals of the USB line. So, instead of 64 KB/s I am only having 64/5 Kb/s data transfer rate.
I have even set my VB software to run in High priority mode - So it has nothing to do with Windows priorities.
Would anyone have a clue how I can increase the data transfer rate ?
Maybe, your distribution is missing some DLL (or OCX) required.
Run Dependency Walker on the target PC for your application EXE. It tells missing DLL, if any.
Dependency Walker www.dependencywalker.com/
See VB6 manual at the chapter of packaging for deployment, to make setup project.
