my experience with my 16GB pendrive and two prtitions (sda1 for boot with 16MB and the rest [sda2] for my files) was that sometimes (mostly after uninstalling some tce extensions), sda2 have been remounted read-only, and then i had not any chance to write in my directories, neither as a user, nor as root; i have reformatted it fat32 with only one partition, and since i don't have any issue of that kind

Assuming your usb stick is formatted with a linux file system, this would depend on what you're trying to modify - usually the root of the file system would be owned (not surprisingly) by root, so if you're trying to add a directory like /myfolder, you would need to be root.

If you've already created a directory /myfolder and set its permissions to tc:staff then you should be able to create/modify directories and files within /myfolder

Your choice of filesystem must be able to support permissions. We don't run everything as root here.
