Thuraya XT satphone - what USB chip is used?

Started by John-Smith February 28, 2014
I am trying to make it work under win8...

It isn't a Prolific 2303 and it isn't an FTDI FT232 or similar...

Win8 does notice it was plugged in (it beeps) but nothing new (that I
can see) appears under Control Panel / Devices.

I would expect a COM port with a Hayes compatible modem behind it.
That is what their older models do. The old 7100 is a straight RS232
Hayes modem, but the XT is USB only.

The modem has a config for two things: Modem and USB. Neither makes
any difference, but the 1st one suggests that perhaps it does have an
RS232 interface...

You might want to plug it into a Linux box (boot a Linux live CD image or USB stick on your current machine, if you wish) and do an "lsusb" and "lsusb -v". This should show you plenty of information about the device characteristics. An increasing number of devices these days are publishing a CDC (Communications Device Class) endpoint... behaves a lot like a modem or serial port but there's no concept of baud rate.

Interesting. Is there a Linux image which can go onto a USB flash stick and "just work"? Years ago I had something like that on a boot CD. But for this experiment I obviously need something much more current. One unix user reports that the Thuraya phone worked straight off, detecting it as a Hayhes modem and with a popup asking for the APN! Somehow it must have assumed that this is not a DUN device but a GPRS/3G device, knew the number to dial is *99#, and just needed the APN and the login/pwd.

Ubuntu will, though it does take some googling to figure out how to make that USB flash anyway, in windows you can use usbview from MS, can get it here: http://www.ftdichip.com/Support/Utilities/usbview.zip -Lasse

Quite a few Linux distributions come, or are compatible with USB-stick imaging programs.. http://www.pendrivelinux.com/ has pointers and instructions, including a "Universal USB Installer" app for Windows which can image many different sorts of bootable image (Linux and otherwise) onto a USB stick. Ubuntu seems to recommend this installer as the best way to get a bootable Ubuntu stick. http://www.debian.org/CD/live/ has live-install images for CDs and USB sticks. Naturally, such imaged USB sticks will only boot on systems whose BIOSes possess this capability... which is most modern ones, I believe.

There's tons of microcontrollers on the market with USB ports. If you're building 1000 a year or more of something it's probably worth the trouble to make that work rather than wasting money and board space on a separate chip. -- Tim Wescott Control system and signal processing consulting www.wescottdesign.com

Ubuntu does that very well. I'm sure there's others, but I'm only familiar with Ubuntu. -- Tim Wescott Control system and signal processing consulting www.wescottdesign.com

Yes, but equally the equipment manufacturer is not going to be writing their own windows drivers for any of these, because that is an absolute pig of a job. I wonder which of these are the main players? I will try that USB monitoring program, from the FTDI website. I know FTDI - we use them at work. Good chips and a good company.

You could implement a CDC class device, and use the standard drivers.

I tried that - thanks. Here is an update, to recap: Windows doesn't show it as any device whatsoever, in Control Panel/ Devices. According to Thuraya, win8 is not supported. Now this could just be a script monkey reply, so I investigated further. Google turns up a driver but it turns out to be the usual scam which is an executable which scans your computer (or pretends to) and then finds loads of "problems" and offers to fix them... yeah right. I downloaded a USB analyser from http://www.ftdichip.com/Support/Utilities/usbview.zip (a known good company which makes USB chips) and this shows all devices I connect, via a hub perhaps, but for the phone it shows absolutely nothing. No device ID, no device name, nothing. The Lenovo Tablet 2 beeps when the phone is connected or disconnected so it has seen "something" allright but that is the only indication of life. The phone offers two configs for the USB port: "USB", and "modem" and for the latter they offer a baud rate setting. Neither of these two does anything. Presumably Thuraya are using some microcontroller with a USB Slave interface, but whose? It isn't Prolific or FTDI who are the two main players in that business. I have tried running the phone under a winXP VM but the Thuraya winXP software says the OS version is invalid and won't install. I tried installing the win7 driver under a win7 compatibility mode and it installs but doesn't do anything.
