I FINALLY got virtualbox running and the usb recognized, and a separate disk created so i can convert the running image disk in vm to an iso file. Took me a few days as it was very difficult getting VirtualBox to even recognize the USB. Had to run terminal command to sign me into VirtualBox groups, which took me a long time to find out about- it was a nightmare- it shouldn’t be that hard or the info so buried that the average user will not be able to find it. (I really probably shoulda used VMWare instead- but i was stubborn and wanted virtualbox to run as it should-)
Anyways- now I’m updating the windows install znd adding in a few programs like photoshop, tweaking it how i like it, and then gonna try to convert the vm image to an iso following the video from brightec09 here (i might given the link before?)

Will update if I am successful, but will be a few days
Good luck with Photoshop on there.. it will be very slow and clunky.. (remember I mentioned VB is like an 18 wheeler with 15 wheels?)
The problem is that it creates its own virtual PC (obviously) that is missing out on the use of many of the actual PC's capabilities (so some programs won't even work), so it is limited on resource use.
VMWare is better, but is is a MAJOR PITA...
(was for me, anyway) (Remember Kinguin? VMWare was on sale for under $1! Don't have to buy it, but it would get you better tech support, and more options):
I still recommend trying out Lutris, which PS ran smooth as a hot knife through butter for me.
