This is a note to let you know that I've just added the patch titled
usb: cdc-acm: add quirk to blacklist ETAS ES58X devices
to my usb git tree which can be found at
git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/usb.git
in the usb-testing branch.
The patch will show up in the next release of the linux-next tree
(usually sometime within the next 24 hours during the week.)
The patch will be merged to the usb-next branch sometime soon,
after it passes testing, and the merge window is open.
If you have any questions about this process, please let me know.

Subject: usb: cdc-acm: add quirk to blacklist ETAS ES58X devices
The ES58X devices has a CDC ACM interface (used for debug
purpose). During probing, the device is thus recognized as USB Modem
(CDC ACM), preventing the etas-es58x module to load:
usbcore: registered new interface driver etas_es58x
usb 1-1.1: new full-speed USB device number 14 using xhci_hcd
usb 1-1.1: New USB device found, idVendor=108c, idProduct=0159, bcdDevice= 1.00
usb 1-1.1: New USB device strings: Mfr=1, Product=2, SerialNumber=3
usb 1-1.1: Product: ES581.4
usb 1-1.1: Manufacturer: ETAS GmbH
usb 1-1.1: SerialNumber: 2204355
cdc_acm 1-1.1:1.0: No union descriptor, testing for castrated device
cdc_acm 1-1.1:1.0: ttyACM0: USB ACM device
Thus, these have been added to the ignore list in
drivers/usb/class/cdc-acm.c
N.B. Future firmware release of the ES58X will remove the CDC-ACM
interface.
