Problems with ezusb.sys driver

[Anonymous]

Hi everyone.

   

I'm using old ezusb.sys driver to communicate with CY7C68013 USB chip.

   

Where can i find a documentation on a ezusb.sys?

   

I faced with some problems using it. I'm doing send and receive operations (BULK transfer). The question is what happens with packets if they are send to PC but not read with IOCTL_EZUSB_BULK_READ. Does ezusb.sys uses an internal buffer?

   

Where can i read about theese things?

   

Thanks in advance.

Hi

   

You may find your information in "Cypress (On C Partition Root)\USB\Doc\".

       

You need to install "Cypress FX2 Developers Kit" to see these files.
