From 8903795a5275e0366acf961190c57074ad27f9bb Mon Sep 17 00:00:00 2001 From: Alan Stern Date: Tue, 13 Feb 2007 14:55:27 -0500 Subject: EHCI: turn off remote wakeup during shutdown This patch (as850b) disables remote wakeup (and everything else!) on all EHCI ports when the shutdown() method is called. If remote wakeup is left active then some systems will reboot instead of powering off. This fixes Bugzilla #7828.

It does not bind to the device, so all userspace programs can still sync properly with it. Note, if CONFIG_USB_SUSPEND is enabled, it can play havoc with this device as the power to the port will be shut down. This device id will have to be added to the global blacklist table when it is created.

I added two fields to struct usb_serial_port to keep track of the throttle state. Other usb-serial drivers typically use private data for such things, but the generic driver can not really do that because some of its code is also used by other drivers (which may have their own private data needs). As it is, I am not sure that this patch is useful in all scenarios. It is certainly helpful for low-bandwidth devices that can hold their data in response to throttling. But for devices that pump data in real-time as fast as possible (webcam, A/D converter, etc), throttling may actually cause more data loss.

The return value of gs_setup_class() is treated as the number of bytes to write in the status phase of the control request, by gs_setup(). For this case, the value returned by gs_setup_class should be zero for SET_LINE_CODING but, right now, appears to be sizeof(struct usb_cdc_line_coding). However, if after doing the memcpy of the line coding descriptor we set the variable "ret" to be zero, we should return the appropiate ZLP to the host as an ACK in the status phase of the control request. I've tested this out using Linux as both host and slave and confirmed that the following small change fixes the spurious return of sizeof(struct usb_cdc_line_coding)/wLength bytes in the status phase of a USB_CDC_REQ_SET_LINE_CODING request.

This patch (as852) allows usb_set_configuration() to accept a config value of -1 as indicating that the device should be unconfigured. The request actually sent to the device will still contain 0 as the value. But even if the device does have a configuration 0, dev->actconfig will be set to NULL and dev->state will be set to USB_STATE_ADDRESS. Without some sort of special-case handling like this, there is no way to unconfigure these non-compliant devices.
