Hi,
I suspect that your problem might have something to do with suspend/resume
support.
Assuming your device is High Speed, could you edit:
/sys/dev/usb/controller/ehci.c and find the function:
ehci_set_hw_power()
There you change:
if (flags & (USB_HW_POWER_CONTROL |
USB_HW_POWER_BULK)) {
DPRINTF("Async is active\n");
temp |= EHCI_CMD_ASE;
}
if (flags & (USB_HW_POWER_INTERRUPT |
USB_HW_POWER_ISOC)) {
DPRINTF("Periodic is active\n");
temp |= EHCI_CMD_PSE;
}
Into:
if (1) {
DPRINTF("Async is active\n");
temp |= EHCI_CMD_ASE;
}
if (1) {
DPRINTF("Periodic is active\n");
temp |= EHCI_CMD_PSE;
}
Lookup ohci_set_hw_power() and uhci_set_hw_power() and patch likewise.
