Hi Lauren, quick update below.

The unpopulated potential FX2 (and other unpopulated pads) from 6022BE are gone in the 6022BL, at least in the version that I have. The other FX2 is used for both functionality (either scope or LA, but you cannot have both at the same time apparently). Teardowns from me for both devices: http://sigrok.org/wiki/Hantek_6022BE http://sigrok.org/wiki/Hantek_6022BL > Presumably they have different USB > product IDs as well. There's also lsusb info for all devices and cases linked from the wiki pages above. The 6022BL (my model at least) has a button which controls with which VID/PID it comes up. Either 04b4:602a (scope usage) or 0925:3881 "Lakeview Research Saleae Logic" (Saleae Logic VID/PID, so fx2lafw works out of the box as 8-channel 24MHz logic analyzer). (No, this is not a Saleae Logic16 clone, that's a completely different device, firmware, FPGA bitstreams, etc. etc.) It *might* be possible to use it as 16-channel FX2 based LA as well (at max 16MHz samplerate then), but that's currently not possible out of the box since the VID/PID suggests an 8-channel Saleae Logic, which we use/assume in firmware and libsigrok. I also haven't verified yet if the correct pins are even used on the PCB to make this possible. > And that's as far as I can get.

That has changed yesterday, a basic driver written by Christer Ekholm is now merged (thanks a lot!). Testing would be highly appreciated. The driver might need some more work, but it's a good start. http://sigrok.org/gitweb/?p=libsigrok.git;a=summary Also, I've merged (with minimal changes) the 6022BE open-source firmware written by Jochen Hoenicke (thanks a lot!) into fx2lafw for user convenience. Details: http://sigrok.org/gitweb/?p=sigrok-firmware-fx2lafw.git;a=summary http://sigrok.org/gitweb/?p=sigrok-firmware-fx2lafw.git;a=commitdiff;h=189db3d41e4c3d8a4aec5ec605c03df75577d531 I.e. to use this you have to have the latest libsigrok from git and the latest sigrok-firmware-fx2lafw from git and it should work out of the box (use the udev rules file if needed etc). I've only tested 6022BE so far (scope) and 6022BL (LA mode). Getting the 6022BL (scope mode) to work may or may not require some more changes, I'll look into that.
