Can't access Motorola Milestone on Ubuntu 9.10 via adb (HTC Magic works perfectly fine)

I've two phones, the HTC Magic and since today also the Motorola Milestone.

While the Magic works perfectly, I'm not able to access the Milestone via USB (adb devices).

Here are my log outputs and settings for both:

Notes

• USB Debugging is enabled on both phones
• After changing the udev rules I did a "service udev reload" and "adb kill-server" -> didn't help
• I even tried to restart the whole machine. Without success.

Anyone encountered a similar problem and had a solution?

---

The problem is, as usual, simpler than expected. Even though USB debugging is enabled you additional have to pull down the notification bar and go to USB connection.

There you have 4 options:

• Motorola Phone Tools
• Windows Media Sync
• Memory Card Management
• None

Here you have to select "None"

After that everything works fine.

I actually had to use the "Memory Card Management" option for it to work on Ubuntu 8.10. In "None" mode it would not mount.

---

Note that for some newer phones, rather than selecting None, PC Mode might also work as well. I spent a good 45 minutes trying to get this to work when all I had to do was set it to that.

Note

This is on Ubuntu 12.04 LTS.
