CY7C68013A and error code 997
I am beginning to use a CY7C68013A , It's connected to a FPGA Altera Cyclone (I), I've connected the USB Chip to the computer and I've modified the cyusb.inf file using the VID=04B4 and PID=8613 (default), in the device manager it's seems OK, but i have noticed that when i change VID or PID to a different value still in the device manager it's OK,.
I've used "USB Control Center" to send some bytes to the USB Chip (default firmware) but it doesn't work , it gives the message :
BULK OUT transfer
BULK OUT transfer failed with Error Code:997
Should it work?or i need to program a different firmware??
Then i have tried with the example "Designing with EZ-USB FX2LP Slave FIFO Interface using FPGA " (just used slave.hex)
and the Device manager shows the VID= 04B4 and PID=00F1, I've modified the "cyusb.inf" file usind the new VID and PID, but the Device manager of my windows 7 shows :
The drivers for this device are not installed. (Code 28)
The install class is not present or is invalid.
To find a driver for this device, click Update Driver.
So, i've tried update the driver using the driver from C:\Cypress\Cypress Suite USB 3.4.7\Driver\bin\wlh\x64 (It's same path of cyusb.inf)
"The install class is not present or is invalid" (look in DevManager.png)
I hope someone can help me.
thanks in advance
