    serial to USB support for XM?

    just so I dont keep killing myself over this: Does ME allow for virtual comm ports?

    When I go to enable the XM in the cfg, it will now allow me to check the box to enable it. When I do it manually in the CFG file, It wont pick up my tuner.

    ideas?

    All the PCR tuners contain a USB>Serial adapter, so yes, guessing that what you're doing is using a USB>Serial connected to an XMD, it should work for you.

    What kind of USB>Serial adapter are you using, and can you elaborate a little on what you mean by: "it will now allow me to check the box to enable it"? The reason I ask is because I don't think there's any logic to disable the checkbox. There are a handful of reasons why you might be having this issue, so the more detail you give about your setup the greater the likelyhood I'll be able to help. Checking your debug.log file and posting your settings.ini file would be a good idea too.

    I will do a re-format today, or Saturday and get back to you. My windows install is a bit loco right now.

    But the thing that it wont even do is search my comm ports for an active serial connection. When you check the box on my computer, it actively scans for the tuner. However, on my CarPC, when you check the box, it will not scan and automatically un-check the box.

    It's probably not seeing any com ports - look at the remote tab and see what / how many com ports are listed there. If it's not showing any, but you do see them in device manager, then it could be an issue with some of the routines I'm using to detect the number of ports.

    Out of curiosity, what OS are you running?

    Now that I re-installed winblows, it does see the comm port. However, it will not get a ping back =/

    Webdog on these forums made me the cable, and he was using it on his computer before I. Something is amiss....

    No loopback = you have a driver and / or a hardware issue.

    I've used a couple different USB>RS232 adapters in my carpc, and have had no problems with them other than issues that stemmed from a flaky USB hub I was using. I replaced it with home-runs to the motherboard USB ports and I've been problem free since. I'm using one for my IR remote, it's a no-name brand affair based on the Prolific chip. Think I'm using the drivers that came with my Delorme GPS adapter.

    Do you think its really the driver? I am using the Prolific drivers to run my Comm ports. The XM unit is brand new, so do you think its the cable? When I plug in the usb winblows sees it and ding dongs, and it assigns it a port.

    It could be many things - you need to pinpoint the problem by eliminating the possibilities. If it's failing a loopback test that's a pretty good indication that you either have a bad loopback cable, the hardware is faulty, or the drivers aren't working. My suggestion is to connect a serial mouse or some other known working serial device to the adapter to verify it's operation. If that works and the xm receiver is still giving you problems then connect the xm receiver directly to a serial port to verify that your cable is good.
