cdc-acm: Add support for Denso cradle CU-321

2015-02-24T16:38:47Z

In order to support an older USB cradle by Denso, I added its vendor- and product-ID to the array of usb_device_id acm_ids. In this way cdc-acm feels responsible for this cradle. The related /dev/ttyACM node is being created properly, and the data transfer works. However, later cradle models by Denso do have proper descriptors, so the patch is not required for these. At the same time both the older and the later model have the same vendor- and product-ID, but they both work with the patched driver. Declaration of the Denso cradles I tested: - both models have the same IDs: vendorID 0x076d, productID 0x0006 - older model: Denso CU-321 (descriptors not properly set) - later model: Denso CU-821 (with proper descriptors) Signed-off-by: Bjoern Gerhart Acked-by: Oliver Neukum Signed-off-by: Greg Kroah-Hartman

We need to check that we have both a valid data and control inteface for both types of headers (union and not union.) References: https://bugzilla.kernel.org/show_bug.cgi?id=83551 Reported-by: Simon Schubert <2+kernel@0x2c.org> Cc: stable Signed-off-by: Greg Kroah-Hartman

USB: cdc-acm: add quirk for control-line state requests

2014-11-06T20:25:40Z

Add new quirk for devices that cannot handle control-line state requests. Note that we currently send these requests to all devices, regardless of whether they claim to support it, but that errors are only logged if support is claimed. Since commit 0943d8ead30e ("USB: cdc-acm: use tty-port dtr_rts"), which only changed the timings for these requests slightly, this has been reported to cause occasional firmware crashes on Simtec Electronics Entropy Key devices after re-enumeration. Enable the quirk for this device. Reported-by: Nix Tested-by: Nix Cc: stable # v3.16 Signed-off-by: Johan Hovold Signed-off-by: Greg Kroah-Hartman
