Hello,
I am trying to send commands to a keyboard to set the idle rate and
confirm that it's been set like below,
#define SET_IDLE 0x0A
#define GET_IDLE 0x02
unsigned char data[1] = {0};
ret = usb_control_msg(dev,
usb_rcvctrlpipe(dev, 0),
SET_IDLE,
(0x01 << 5) + 0x01,
0xaa00, 0, data, 0, USB_CTRL_SET_TIMEOUT);
ret = usb_control_msg(dev,
usb_rcvctrlpipe(dev, 0),
GET_IDLE,
(0x01 << 7) + (0x01 << 5) + 0x01,
0x0000, 0, data, 1, USB_CTRL_GET_TIMEOUT);
printk("%02x\n", data[0]);
The printk always gives me a zero but the value of ret for GET_IDLE is
always 1. I've been able to do all of this using libusb in user space
but have no success within a kernel module. I've also looked at
devio.c for reference and have run out of ideas of what could be
wrong. Also, when I try to do a SET_REPORT using usb_control_msg in
the kernel just like with libusb, my host controller shuts down and
breaks like I sent _it_ the command.
Thanks..
