I can't seem to get the GEMMA to pop up as available in the serial port. I've attached a screen print, all seems to have installed correctly. Any thoughts ? I did try the hub without success.
Thanks

Re: Another Gemma issue
The Trinket and Gemma don't appear as serial ports. They pretend to be programmers (the USBtiny item in your devices list).
What you need to do is select 'USBtinyISP' under the Programmer menu.

Re: Another Gemma issue
That makes sense. So I verified it's connection, and it USBTiny is installed. I ran this both off the USB 2.0 up and the "native" USB ports. When I upload with programmer, I get
Binary sketch size: 3,490 bytes (of a 5,310 byte maximum)
avrdude: Error: Could not find USBtiny device (0x1781/0xc9f)

Re: Another Gemma issue
Hmm.. that error usually pops up when you haven't loaded the driver.
Have you loaded the driver, and if so, which version? Our original version is unsigned, but we've been working on a signed version to keep the Windows security system happy.

Re: Another Gemma issue
It's showing in my device manager ...I think the screen print in my earlier post shows it.
I am going to delete everything and start all over again.
Frustrating but hey - this is part of the fun.....

Re: Another Gemma issue
Are you sure you have the bootloader timing right?
When you press the reset button the onboard LED will pulse for about 10 seconds. That's the period where the bootloader is active and waiting to read input from the USB cable. You need to time your compile-and-load operation in the Arduino IDE so it syncs up with the bootloader window. That can be a challenge with the Windows device manager.

Re: Another Gemma issue
Success - I am embarrassed to say that I completely forgot about the bootloader timing in all the chaos. Sorry - Thanks for being patient.

Re: Another Gemma issue
New systems are only obvious *after* you've gotten them to work a couple of times.
Glad to hear you finally got things working though. Happy hacking!
