My Sony PCG-FXA47 laptop occasionally gets the error message: usb0: host controller process error usb0: host controller halted usb0: regs: ... bunch of register values ... The USB device is a GPS unit (with a USB-to-serial adapter lump in the cable) recognized as ugen0. I suspect that this error happens because the cable connection isn't perfectly solid. My question: is there a way I can *UN*halt the host controller (manually, with a userland command, which I'll write if necessary) after it's halted, short of a reboot? Perhaps something like ioctl(fd, TIOC_USB_RESET_HOST_CONTROLLER_DAMMIT, 0); Disconnecting and re-connecting the device doesn't work (it won't power up). Gordon L. Burditt
