Hi @Diana Cline ,
based in this three facts
- without a password
- without the recovery key
- without the original computer
you won't be able to decrypt the USB stick.
For exactly this kind of scenario the bitlocker encryption for usb sticks is made/designed for:
- Someone lost the encrypted usb stick somewhere
- Someone else found the usb stick and without password/recovery key he can't get access to the encrypted data
Sorry for no better news.
