I have found a Linux C program that controls the K8055 board. I am trying to adapt this to the K8090 board. So far I have the board being recognized by the Linux OS.
usb 1-1: New USB device found, idVendor=10cf, idProduct=8090
usb 1-1: New USB device strings: Mfr=1, Product=2, SerialNumber=0
cdc_acm 1-1:1.0: This device cannot do calls on its own. It is not a modem.
cdc_acm 1-1:1.0: ttyACM0: USB ACM device
Under my own program control using parts of the K8055 program, the terminal output is:
Velleman Device Found @ Address 004 Vendor 0x010cf Product ID 0x08090
Got driver name: dummy
Disconnected OS driver: Success
usb 1-1: usbfs: interface 0 claimed by usbfs while ‘k8090’ sets config #1
Found interface 0
Took over the device
As can be seen, the K8090 is enumerated properly but writing/reading to the device is failing. Without disassembling the windows driver, can anyone tell me how many bytes are supposed get sent to the K8090? Where can I find a command list?
Are these two defines proper?
#define USB_OUT_EP 0x01 /* USB output endpoint /
#define USB_INP_EP 0x81 / USB Input endpoint */
