maybe... it depends on how the USB was formatted.
'Disks' can be formatted in several ways. The most common for Windows is NTFS. NTFS is a proprietary file system for Windows and cannot be read by Macs, Unix, Solaris, ect. Mac commonly use HFS+ which is incompatible with other operating systems as well.
There is a catch all. You may have formatted the USB as FAT32 ( I believe FAT32 was/is the default file system for many USB, although I have found many that are NTFS and thus need to be formatted to work on my Macs ). This can be read by most operating systems.
So, maybe is the answer. It depends on how you initially formatted the drive.
