[Virtual-pkg-base-maintainers] Bug#790413: base: index of ttyUSB* is always increased

[Haojian Zhuang]

Package: base
Severity: normal

Dear Maintainer,

When I work with embedded system, ttyUSB is always used. ttyUSB0 is used as
my serial console, and ttyUSB1 is used as downloading image.

The usb port of ttyUSB1 is used as two usages. One usage is for ttyUSB, and
the other usage is just working as USB device. Once I used the usb port as
USB device and I switched it back to ttyUSB for the next time, the index of
ttyUSB is always increased.

If I use this usage model in ubuntu 14.04 system, this issue doesn't occur.
ttyUSB1 is always ttyUSB1, whatever I used the usb port as USB device.
