Kalamatee has been working around the clock for the past few weeks to implement USB3 support in the Poseidon stack. You can read more here.

https://arosworld.org/infusions/forum/viewthread.php?thread_id=1743&pid=10287#post_10287

Once the work is complete, many computers built after 2015 will be able to be used with native AROS!

- USB3 in VMware: you can use your USB stick to read/write data. Note: once the stick is inserted, there may be a 20-120 second ‘freeze’ when AROS is slow to respond.
- USB3 in VirtualBox/QEMU - currently, USB sticks are partially detected in Trident but cannot yet be used.

Deadwood has prepared an experimental ISO of Kalamatee's work, solely for the purpose of testing and reporting on its current status.

https://build.axrt.org/download/builds/Experimental/exp-usb3-pc-x86_64-20251210-063846.tar.gz


If you would like to test the ISO, you can use the same link to confirm that your USB3 hardware has been detected correctly. To verify this, simply go to Prefs/Trident and list the detected devices as shown in the screenshot!

@AMIGASYSTEM

How much do the USB stacks in AROS and the latest MorphOS differ?

@r-tea

I think the only people who could answer that are MorphOS developers. AFAIK Poseidon was first included in MorphOS and then later open sourced and included in AROS.

MorphOS has more usb classes, older ones are bugfixed/extended and drivers have isochronous mode. API is the same.

Hi All,

An updated experimental build of AROS with USB3 support is now available for testing!

More in this thread on Arosworld

@rzookol

which is ironic because since Kalamatee decided to work on xHCI he decided to work on isochronous transfers. as far as number of classes I can't answer I do know there are a few he hasn't committed yet.
