NetBSD neneh 6.1.1 NetBSD 6.1.1 (GENERIC) i386
>Description:
The XSStick W14 is switched to 3G mode by the u3ginit code but since its
USB PID 0x9603 is not contained in u3g_devs no ucom devices are created for it.

>How-To-Repeat:
Insert the XSStick W14 into a USB port of a system running NetBSD 6.1.1

Lacking a kernel build environment this has only be tested using

perl -e 'undef $/; $_ = <>; s/(\x9e\x1c)\x05\x96/$1\x03\x96/; print $_;' 
/netbsd > /netbsd-w14 && cmp -l /netbsd /netbsd-w14

After booting /netbsd-w14 ucom devices are created and AT commands
can be sent to the XSStick W14:
