Sorry to revive an old thread.
Having searched for several days this is the first thread I've found where with contributors having such high level insights into the workings of tethering, Linux, and Pentax..
I have recently acquired a K10D that I need to run tethered using Linux. (Ubuntu)
Unfortunately it will not work with Pktriggercord nor the much older Pkremote.
I had suspected a GTK problem, as smigol had noted with their K10D, until I tried my K200D with the same set up and it worked just fine.
I suspect that, with K10D firmware 1.20 and beyond, the introduction of compatibility with Pentax's own 'Remote Assistant software has broken the Linux operability somehow.
My K10D is running firmware 1.31 which can no longer be downgraded and so I cannot test this.
Pktether does work without any problems but can't be run using Wine (no usb support)
I have tried running it using WinXP in Virtualbox on Ubuntu but there seems to be a known issue in VBox where their claimed usb 2.0 only transfers at 1.1 speeds. This then is also not a workable option.
Has anyone suggestions ?
or light to shed upon this conundrum ?
Comments most welcome..(excepting.."buy a new camera"
