I've recently purchased an "HL USB-RS232" adapter, for my ThinkPad. The package says it's Linux compatible, but there's no instructions for Linux (even the Windows instructions are weak). Does anyone know how I might set up this adapter? tnx jk

Take a look at dmesg and it should show you which tty port to use. Probably ttyUSB0 would be my guess. -- Ken Schneider UNIX since 1989, linux since 1994, SuSE since 1998 "The day Microsoft makes something that doesn't suck is probably the day they start making vacuum cleaners." -Ernst Jan Plugge

My dmesg has wrapped around with debug stuff, but "zgrep /var/log/messages*.gz" shows lots of hotplug events mentioning ttyUSB0. May be there is something in /var/log/messages*.

I looked there, and didn't find anything. As I mentioned in another note, it doesn't work in XP either, so I'm taking it back. tnx jk

I had somethig a few days ago that would not work straight off in XP. It did with SuSE :-))))) Sadly not applicable here but it does show that XP is not the be all and end all. I know, we all know it anyway :-) -- Take care. Kevan Farmer 34 Hill Street Cheslyn Hay Staffordshire WS6 7HR

I took that adapter back, and bought another one that works in both Linux & XP. However, I had to install drivers for it to work with XP.

Oddly enough, I had just this happen on an XP laptop I later installed 9.1Pro on -- I *had* to have a serial port, and this machine has nothing but USB. XP hardware manager recognized the USB->serial port, and added the right drivers, but I could *never* get the associated COM port to open. But on the same machine, under SuSE, it works just fine. Unfortunately, the *software* that needed the serial port is Win-only....

I'd suggest getting something like the Prolific technology PL2303 that definitely works. It's strange that it is recognised, the correct driver and module are loaded, but it doesn't build a device for it. I think there are some problems still with USB hotplug/udev as I have a PhoneSkype USB phone where the audio side works but the keypad doesn't though it is detected in /sys and /proc, hwinfo on the other hand only detects the usb-audio side. Andrew Morton threw that problem to the USB development group, but I've not had a single reply to that and several updates detailing the problem. Regards Sid. -- Sid Boyce ...

I took the other one back, and got a "StarTech" adapter, with that chipset, that worked immediately in Linux and as soon as I installed the drivers in XP. Funny that. Linux is supposed to be more difficult, but Windows requires installing a driver. ;-) tnx jk

The manufacturers usually have to support their products under Windows, MS wouldn't do that for them. On Linux, the manufacturers in the main don't care, so it's left up to the kernel developers to do the best job they can, sometimes without any product data. Many years ago I had a PCI modem that I never got to work with Windows 95 and the best advice I had from the Linux newsgroups was to sell it and buy a standalone modem. I eventually got it working under Linux and was able to help lots of people get their PCI modems working. With Linux, we have to be "smarter than the average bear". I'm still surprised the original didn't work, bad hardware perhaps. Regards Sid. -- Sid Boyce ...

More likely bad design or a run of bad hardware. When I took it back, I tried another one and it too failed. The clerk also tried it on his computer and it was still bad. The bad ones had (IIRC), a Cyprus chip set and I have read that they have problems providing sufficient voltage for RS-232.
