What does btusb.enable_autosuspend=n really do?

Bluetooth is a mess in linux. After hours of trying to make bluetooth even turn on, I found out that adding this to the grub fixed the issue to where now it's at least turning on albeit not pairing with any devices. I went and reconfigured my GRUB legacy in /etc/default/grub and added GRUB_CMDLINE_LINUX_DEFAULT=btusb.enable_autosuspend=n But can someone tell me what this actually did and why it worked? My guess is it's telling bluetooth to not suspend automatically but why would bluetooth do that in the first place when turning on my arch device? I am using Arch linux on a dell with Intel centrum 1000 N
