In two cases, I get a black screen with the build information message two lines of text.

Hmm, weird there should be more output than just two lines. Nothing I can recommend further.

Amiwell, for the USB stick, make sure that it is USB3 and that your PC has a USB3 port.
If you use a USB2 USB stick, it will not work and you will see a black screen.

Amiwell, per la Pendrive accertati che la Pendrive sia USB3 e che il PC abbia una porta USB3.
Se utilizzi una Pendrive USB2 non funzionerà e avrai una schermata nera

have USB 3 ports and the keys are USB 3

Did you use the latest version of RUFUS to burn the USB stick?

Amiwell, make sure that the USB stick is USB3 (it should be written on the USB stick), make sure that legacy is also enabled in the BIOS, start the PC by calling up the menu (on HD it should be F9) and start the USB stick (you should see the name of the USB stick manufacturer).

Start the USB stick, make a video and show what appears on the screen.

Per Masterizzare la Pendrive hai usato l'ultima versione di RUFUS ?

Amiwell accertati che la Pendrive sia USB3 (deve essere scritto sulla Pendrive), accertati che anche legacy sia attivato nel bios, vavvia il PC richiamando il Menu (Su HP dovrebbe essere F9) e avvia la Pendrive (dovresti leggere il nome del produttore Pendrive)

Avvia la Pendrive e fai un video e mostra cosa esce sullo schemo.

I burned the ISO onto a DVD.

Sorry Amiwell, I misunderstood, I thought you were trying AROS portable distribution!

That is exactly what I got when testing my i7 tower system with 64 bit (previously reported here); the odd thing is it runs 32 bit with no issues at all.

Cheers,
Nigel.

Even on my HP ENVY 15-k112nl Intel Core i7 i7-4510U, the Build loads Grub and then restarts the PC with the Windows system.

@ntromans @AMIGASYSTEM,

Please try the latest build from 'Nightly build' thread and report back (in 'Nightly build' thread) if you go further than that. Nighly build ISOs are using newer kernel then these Experimental USB ISOs at the moment.

I'll give this a go at the weekend.

Cheers,
Nigel.

I tried to boot with 32-bit Aros. It manages to start up, but I only have USB 3 ports and it doesn't finish booting.

getting something like this Wirenest USB to Serial Null Modem RS232 Adapter and using a terminal to log the kernel output is useful for debugging...

I am unable to use these tools however the computer there is of 8th generation

New ISO, but this time there are no new USB3 changes. What I would like to ask you however to test, is do regression testing of USB2 support in that ISO: whatever devices you are using regularly with AROS, especially if you are using things like USB network cards.

Try using these devices with this ISO and USB2 ports:

https://build.axrt.org/download/builds/Experimental/exp-usb3-pc-x86_64-20260327-064848.tar.gz

If it doesn't work as intended and you suspect a regression, please try then using the same device with this ISO:

https://build.axrt.org/download/builds/AROS-ABIv11/pc-x86_64-20260325-014650.tar.gz

If it works with second ISO but not with first, it is indeed a regression - please report it here.

If some of your hardware (like maybe USB sound cards?) start working with first ISO but don't work with second ISO, please report it as well - this is new hardware support.

I burned the two experimental USB drive ISOs, but neither of them boots on my PCs; in fact, GRUB isn’t visible at all – there’s just a flashing white dash on a black screen.

With the reference ISO AROS-20250418-1-U3, the USB drive boots normally on the same two PCs up to GRUB, but to start AROS I have to use noacpi.

Hi,

Burned exp3-usb iso onto CDRW and booted okay on usb3 only laptop. As you stated no change in usb3 features. Will try to find something with usb2 as test soon.

Tried on USB2 laptop and could find no regressions

@AMIGASYSTEM

I'm not sure I understand but AROS ISOs cannot be burned into USB pendrives using Rufus, Etcher, etc - they need to be installed via InstallAROS on VMWARE for example. Please install those ISOs to pendrives and try them out in USB2.0 ports.

In fact, the AROS-20250418-1 ‘ISO’ file burned with Rufus (version 3.20.1929 used), as mentioned, works fine; the only error is ‘FONT --TEST-- Not Deleted’: Object not found, but Wanderer boots without any problems.

In fact, previously the ISOs burned with Rufus didn’t work, but strangely, as mentioned, with AROS-20250418-1, AROS from the USB stick boots and works, whereas with the experimental version it doesn’t.

I’ve repeated the tests several times, wiping the USB stick clean each time (I also wiped the boot loader).

Tried the first of the ISOs above with my i5 laptop (fully working USB 2 with normal distribution). The outcomes were:

USB wireless keyboard & trackpad - fine.

USB memory stick SFS formatted - fine

USB memory sitck FAT formatted - is recognised and window opens but there's nothng shown. On the earlier USB 3 ISOs the files were seen but with corrupted names. Would you like me to try the second ISO from above with this?

Reltek 8180 USB wifi dongle - works, can connect to router and ping it.

Additionally, I tried a USB 4-wire resistive touchscreen adapter. This crashed Truident (see below) but also crashes the normal distribution; however, I thought as work was being done on the USB stack I'd report it in case it was of any use.

Cheers,
Nigel.
