Hey folks;
I've been having some 'interesting' issues with a device that I've
happened upon recently. It's an Entrega U1-S9, which is a Serial (DB9
Male) adapter of sorts; I recently aquired it since my Vaio PCG-R505EL
doesn't have any serial port built onto the actual unit itself. I've
spent many days trying to solve this issue myself to no avail, so I
figured I'd turn to the list for some help. I've included some rather
verbose logs and descriptions below, but if those aren't enough, just let
me know and I'll do my best to provide what you're looking for.
The bottom line is that the device simply doesn't seem to be
sending and/or receiving data properly, as after extensive tests, I'm
unable to get a single bit of data in, or out. (Occasionally I'll get a
single byte of garbage, but that's all).
The device has been tested as working on another (Win*) box
without any problems. There's a LED on the front of the device which
remains red when active, but flashes green when there's serial activity.
Basically, I'm operating on kernel 2.5.42 (the reason being that a
lot of hardware in this Vaio requires the newer drivers present in 2.5.x
and not in the 2.4.x series. I realize this may be a problem unto itself,
but I had similar problems with this device on a 2.4.x testbed) When I
plug in the device for the first time, I get the infamous "host
controller halted. very bad" message. The device then seems to operate
in a 'half-working' state whereby the LED will flash a dull green whenever
there's data going out (from the computer), but won't flash anything when
there's data coming in. Regardless of the LED flashing, no data seems to
make it in or out.
I've enabled CONFIG_USB_SERIAL_DEBUG and have come up with some
interesting errors in various logs at this stage:

As a point of interest, the device seems to be assigned
/dev/usb/tts/0 and /dev/usb/tts/1 when it's first plugged in. Then, when
I remove it and plug it in again, the LED stays a solid red, and doesn't
flash green at all regardless of data flowing in or out of the device.
The driver then assigns it /dev/usb/tts/2 and /dev/usb/tts/3, which would
hint at the fact that something's not being released when it's unplugged:

I've installed the latest hotplug and spent many hours configuring
and tweaking that, so somehow I doubt it's that. (Bypassing hotplug and
inserting all the modules by hand has the same effect, also)
Transmitting on the device brings this in the dmesg:
drivers/usb/serial/keyspan_pda.c: keyspan_pda_write(1)
drivers/usb/serial/usb-serial.c: serial_ioctl - port 2, cmd 0x5415
drivers/usb/serial/usb-serial.c: serial_chars_in_buffer = port 2
drivers/usb/serial/usb-serial.c: serial_chars_in_buffer = port 2
drivers/usb/serial/usb-serial.c: serial_chars_in_buffer = port 2
drivers/usb/serial/usb-serial.c: serial_write - port 2, 1 byte(s)
So, I'm at a loss as to what might be wrong here. I've also
included the output from 'lspci -v', which may be useful. Again, if I'm
missing anything, let me know, and I'll go fetch the information for you
:)

And as a closing note, the USB controller seems to work great with
other devices. I've got two Logitech 'Wingman' USB joysticks, and a Kodak
DC-260 Digital Camera, and all three devices work nicely. Anyway,
hopefully I didn't spam the list too badly, thanks in advance ;)
