Did you check all the way to your connector and from that through the cable? Quarz parameters are missing. That was exactly what I’ve done. Now I’m wondering what else could I check. I’m using self powered configuration, so the chip gets its power from USB port directly. How can I tell these chips apart in Linux? Default decoupling practice should be one 0.

Ryan 1 6 What do you think, is the layout correct? On Windows I got “This device cannot be started” and on Linux some similar errors but no successful connect.

This should work with most cables.
Post as a guest Name. You can tell udevd to assign specific names to the ports based on their physical connection, by creating rules that match against specific DEVPATH.
I’m using self powered configuration, so the chip gets its power from USB port directly. Can I measure some pins for getting more information on what’s going on?
Virtual COM Port Drivers
I need some way of making sure the processes running on my board are using the correct serial channel every time the device starts up. FTDI drivers may be distributed in any form as long as ftdii information is not modified. See above FT datasheet, schematic in chapter 6.

It would detect a low speed device in this case. Knee-jerk response would be it looks like you may not have enough decoupling.

There is no way for these devices to ever be “removed”, “disconnected”, or moved to a different physical USB location. Bus Device Now I’m wondering what else could I check.
On Windows I got unknown device and then Windows disables it because thinks it works wrong. How to identify multiple USB-serial adapters under Ubuntu When you say it’s almost the same it’d be worth including a schematic of what you built.
Yes, you are right, here it is: Quarz parameters are missing. Mac OS X Daniel – We can’t tell you anything about your layout unless you actually post your layout. You might want to double check that.
