[Bug 1243607] Re: Ubuntu 13.10 pl2303 hl340 64 bits problem
Would it be possible for you to test the latest upstream kernel? Refer
to https://wiki.ubuntu.com/KernelMainlineBuilds . Please test the latest
v3.12 kernel[0].
If this bug is fixed in the mainline kernel, please add the following
tag 'kernel-fixed-upstream'.
If the mainline kernel does not fix this bug, please add the tag:
'kernel-bug-exists-upstream'.
If you are unable to test the mainline kernel, for example it will not boot, please add the tag: 'kernel-unable-to-test-upstream'.
Once testing of the upstream kernel is complete, please mark this bug as "Confirmed".
Thanks in advance.

Title:
Ubuntu 13.10 pl2303 hl340 64 bits problem
Status in “linux” package in Ubuntu:
Incomplete
Bug description:
I installed a fresh Ubuntu 13.10 64 bits in a new Asus I7 A55A. Standard install . All run perfect.
I connect a USB-Serial adapter model HL340, it has pl2303 chip but NEVER appear the /dev/ttysUSB0 device.
In other machines I found inmediatelly a new
/dev/ttyUSB0
and all work perfectly.
I see in dmesg, signal that a device is connected
usb 3-1: new full speed USB device using uhci_and address 3
But in the Asus i7 the device never appear.
I run
# lsusb
Bus 008 Device 002: ID 0a5c:217f Broadcom Corp.
Bus 008 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub
Bus 007 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub
Bus 002 Device 036: ID 2773:0104
..........
Bus 002 Device 036: ID 2773:0104
and see others devices (v 1.1, v2 and v3) BUT I don't see the device.
I read near 100 internet pages and Found this
# modprobe pl2303 vendor=0x4348 product=0x5523 --force
And I found it in
# lsusb
Bus 003 Device 003: ID 4348:5523 WinChipHead USB->RS 232 adapter with Prolifec PL 2303 chipset
But again, i never found the
/dev/ttysUSB0
I have some dudes:
* the hardware is HL340, but the module should be usbserial? pl2303? both?
* i used the --force to load the module, but Iḿ not sure is the right module.
* In a 32 bits environment it works as /dev/ttysUSB0, may be the 64 bits is the problem?
* Its a very know hardware, but it doesn't work with 13.10 and 10-2013 ?
