Breakout boards / Re: What breakout do you need/want?
I can't think of anything to do with the actual PCIe bus, but I thought it might be cool to be able to make something using the USB bus, but hidden inside my laptop. Something like a LED bargraph showing CPU load, or a hardware password manager.

Hardware biz / How do you design for pick-n-place?
I've seen plenty of PCB tutorials regarding Eagle and I have gotten my own PCBs made before, but how do you design something that can be assembled on a pick-n-place machine? What files do I need to export and how? How do I design my custom components? What do I need to look out for? I'm looking for info that's specific to Eagle right now.

Also I've seen http://www.youtube.com/watch?v=VXE_dh38HjU which is pretty neat but it's too general

Open Bench Logic Sniffer / Re: "Capture Aborted! Device Not Found!" after update
I just wondered about the CDC stuff because I have a genuine Saleae Logic, and a Saleae Logic clone from ITead Studio called Mini Logic (which also works as an USBee and Altera USB Blaster). ITead Studio was able to reverse engineer the Saleae Logic and USBee so that he can make a clone that is compatible with their software (which wasn't hard, I think the Cypress chip is basically a USB FIFO bridge in all three cases, configured via EEPROM, the clone just had several EEPROM settings to load). I do have a software USB packet analyzer. I would like to see if it is possible to achieve the same thing with the OLS.

Great work with the open source stuff, but the USBee client software can analyze USB packets at a low level, which I hold in high regard

[16/01/11 10:19:59 PM - INFO  -     nl.lxtreme.ols.client.Host]: LogicSniffer v0.9.0 started ...

the new 0.9.2 does not show the same errors and now it works, sort of, data captured at various settings display data that is obviously wrong and sort of patterned, sometimes it starts and never finishes capturing

ps, why are we using CDC and not USB bulk transfers?

Open Bench Logic Sniffer / "Capture Aborted! Device Not Found!" after update
I got the sniffer back in July of last year, the lack of RLE back then made me never use it.

I just checked back, downloaded the latest windows installer, and ran all the upgrades. Now I can't capture any data. It says "Capture Aborted! Device Not Found!" when I try to start a capture.

The COM port is selected correctly (COM11, Logic Sniffer CDC-232). No other software is using the same COM port. VID is 04D8 and PID is FC92. The PWR LED is on, ACT LED is off, TRIG LED is on, ARM LED is off.

If I go into update mode, PUMO loader reports:
Opening serial port 'COM11' @ 921600 ... OK
Found PUMP HW: 1, FW: 2.1, Boot: 1
Found flash: ATMEL AT45DB041D

Downloading and re-installing the mchpcdc.inf does not help
I cannot find a way to re-assign the COM port number
Java is up-to-date
I'm running Win7 Pro 64-bit with test mode enabled (driver signing disabled)

edit: oh sorry I didn't realize this was some sort of new client with a bug report thread already
edit: wow you guys need a bug tracker instead of one massive thread, I was going to repost this to the thread and ask you to delete this one but now I don't know what's a better idea so I'll let the mods decide

edit: I just ran the old "classic" client and the rocket button doesn't do anything, no error messages, the diagram and tools menu are greyed-out

Open Bench Logic Sniffer / Re: erratic data after period of capture
i have the right binary loaded, the pins are right
it works as expected with RLE off, i just find the 16k sample depth disappointing, seeedstudio is advertising 24k depth but i don't even see that option
right now i pretty much do not have a good way of viewing USB device enumeration at 20mhz sample rate, even at 10mhz, there isn't enough sample depth to bridge the massive delay between connection and enumeration, hence why i really REALLY need RLE to work

Open Bench Logic Sniffer / erratic data after period of capture
i'm having some issues getting a good capture, the trigger works as expected every time, but after a period of capture, all of the sudden all 8 channels become erratic, even the signals which are always supposed to be tied to 3.3V

screenshot is attached

what i expect to see is USB traffic on channel 1 and 2, channel 0 is connected to my AVR's reset pin, D- on channel 3 is used as the trigger

there seems to be a visual pattern to this madness, i think there might be a synchronization issue? see attached screenshot for what i mean and also i've included my settings
i've recently updated to everything in the 2.1 release package
running win7 ultimate 64 bit in test mode
