Hello there people,

I'm a newbie here in the forums and I think my question belong here in this subforum, if don't, please forgive me...

Well, since when I bought my computer, Dell Vostro 3550, I installed linux Mint on it and the bluetooth never worked, and I thought it could be a hardware problem. But I had to install windows because I have to use several programs on it, because my teacher at university insist to use a crap program in windows... But that is not the point. After installing windows, the bluetooth was there, working perfectly, and when I restarted back to Mint, the bluetooth worked too!

This is very weird, I can only use bluetooth on linux if I start windows and reboot back to linux, and just one time! So, do you know why that happen? How can I fix that and make bluetooth work every time, without booting windows first?

I have tried several things, installed another bluetooth managers, restart the services, but none of them worked =(

Thank you for your attention,

It sounds like Mint is either not loading the firmware at all or loading incorrect firmware.
When you boot into Windows, the firmware is loaded and when you do a soft reboot, the bluetooth card retains the firmware that was loaded by Windows.
Your laptop has a modern Wlan/Bluetooth combo card. Some of these cards have an error in that they report themselves as bluetooth devices before the firmware is loaded. In Linux, this causes the firmware to fail to load.
Try using the backports version of Mint as that is more likely to contain bug fixes for this issue.
(I had a similar issue on my HP with Debian squeeze)
