Hourglass in corner?

[Dksz]

Hello everyone,
I am trying to add some programs to my HP Prime, but every time I plug it into my computer, I get a loading/hourglass symbol in the corner. I have made sure that I have the most recent version of the connectivity kit, I am using the stock cable(and I have tried others), I have tried on both Mac and Windows (both 10 and 11), I have factory reset the calculator, and tried USB 2 and 3. I don't know what else to do. If any one has any suggestions, please let me know.

Hourglass is the symbol whenever hp prime is calculating or gets stuck in loop.Try entering recovery mode by holding sym and on button.Is your pc recognizing the Prime?If not then your prime's usb port must be defective .Use these functions to check Usb(),Usbsend()?
