2007-12-22USB: New device ID for the CP2101 driverMartin Kusserow1-0/+1
attached please find a new device ID for CP2101 driver. This device is a usb stick from Dynastream to communicate with ANT wireless devices which I suppose is fairly similar to the ANT dev board having product id 0x1003.

2007-12-17USB: revert portions of "UNUSUAL_DEV: Sync up some reported devices from Ubuntu"Greg Kroah-Hartman1-8/+0
This reverts one change from 67fa10627ec0d8aa16f1cf38cf527e67d8097d3c that prevented userspace from seing the "driver disk" lun in a san disk device. The kernel shouldn't do this, it's up to userspace to handle this properly, if it somehow wants to filter this away.

2007-12-17usb: Remove broken optimisation in OHCI IRQ handlerBenjamin Herrenschmidt1-10/+13
The OHCI IRQ handler has an optimisation that avoids reading some chip registers when the controller reports that the interrupt was triggered *only* because completed requests were written into the controller's "done list" and handed to the host. This mechanism can't be used on some controllers. Among others, it fails for the SA1111 and the AMCC 440EP PowerPC processor. This patch removes the optimisation and makes the code clearer.

2007-12-17USB: at91_udc: correct hanging while disconnecting usb cableNicolas Ferre1-0/+2
Correct hanging while disconnecting the USB device cable. Prevent a race between vbus and UDP interrupts. This bug was tracked on at91sam9260ek boards. A usb resume interrupt was firing after the vbus interrupt : the IP was then already stoped and not able to deal with it (no more clock). A simple interrupt disabling is ok as the "end of bus reset" irq is non maskable and ok to resume the USB device IP.

2007-12-17USB: use IRQF_DISABLED for HCD interrupt handlersAlan Stern6-10/+9
Host controller IRQs are supposed to be serviced with interrupts disabled. This patch (as1026) adds an IRQF_DISABLED flag to all the controller drivers that lack it. It also replaces the spin_lock_irqsave() and spin_unlock_irqrestore() calls in uhci_irq() with simple spin_lock() and spin_unlock(). This fixes Bugzilla #9335.

This adds a device ID for the Aerocomm Radio Modem, which uses the cp2102. I'm sure changing num_bulk_in/num_bulk_out to NUM_DONT_CARE is the wrong fix, but this is the only device I have with a cp2102, so I have no idea what a good global value would be, if there is one.

When a device cannot handle the smallest previously limited transfer size (64 blocks) without stalling, limit the device to the amount of packets that fit in a platform native page. The lowest possible limit is PAGE_CACHE_SIZE, so if the device is ever used on a platform that has larger than 8K pages, you lose unless you can convince the device firmware folks to fix the issue.

Revert 7eea436433b7b18045f272562e256976f593f7c0. Lucy said: This patch will work with the 19HS but WILL BREAK all other Keyspan adapters. It will take me a few days to get to looking at a correct fix but that keyspan_send_setup(port, 1) (and the '1' is the important part) must happen once when the port is first opened. The cflag can just be set to whatever the normal default is for your serial environment. So revert this again pending the proper fix.

2007-11-28USB: uevent environment key fixAlan Stern3-35/+25
This patch (as1010) was written by both Kay Sievers and me. It solves the problem of duplicated keys in USB uevent structures by refactoring the uevent subroutines, taking advantage of the way the hotplug core calls uevent handlers for the device's bus and for the device's type. Keys needed for both USB-device and USB-interface events are added in usb_uevent(), which is the bus handler. Keys appropriate only for USB-device or USB-interface events are added in usb_dev_uevent() or usb_if_uevent() respectively, the type handlers. In addition, unnecessary tests for NULL pointers are removed as are duplicated debugging log statements.

Two main issues fixed here are: - An improper use of in-struct lock to protect an open count - Use of urb status for -EINPROGRESS Also, along the way: - Change usb_unlink_urb to usb_kill_urb. Apparently there's no need to use usb_unlink_urb whatsoever in this driver, and the old use of usb_kill_urb was outright racy (it unlinked and immediately freed). - Fix indentation in adu_write.

2007-10-25USB: fix interface sysfs file-creation bugAlan Stern1-1/+7
This patch (as1005) fixes a rather subtle problem. When usb_set_configuration() registers the interfaces and their files in sysfs, it doesn't expect those files to exist already. But when an interface is registered, its driver may call usb_set_interface() and thereby cause the sysfs files to be created. The result is an error when usb_set_configuration() goes on to create those same files again. The (not-so-great) solution is to have usb_set_configuration() remove any existing files before creating them.
