Hi,<br>
<br>
Looks like there is a problem with USB modems (in my case a Huawei<br>
E372) =A0on 2.6rc1 and 2.6rc2. The modem is recognized and listed in<br>
/var/log/messages, as well as with &#39;lsusb&#39;, but no /dev/ttyUSB* spe=
cial<br>
files are created. I had no such troubles on 2.5. Between the working<br>
2.5 and the current, non-operating state there where only two &#39;sudo apk=
<br>
-U upgrade&#39; (to 2.6rc1 and later 2.6rc2, both with reboot afterwards)<b=
r>
and no other changes to the Alpine system.<br>
<br>
At this stage, I cannot pinpoint the problem. Kernel module &#39;usbserial&=
#39;<br>
is loaded and a generic USB-to-serial adapter is recognized and the<br>
corresponding special file created. My educated guess therefore is an<br>
issue with &#39;usb_modeswitch&#39; which can access the USB modem, but exi=
