Important note to users of Iridium 9555 and 9575 handsets:
We are getting reports of Iridium USB driver incompatibility with Windows 10 systems.
We have confirmed that a PC upgraded to Windows 10 will not work with an USB connected Iridium handset. Open the port to connect to the phone results in an instant BSOD crash.
We have not confirmed if this also happens with PCs originally shipped with Windows 10. If you have more information, please let us know.
Iridium is aware of the problem and is working on a solution. They have not, however, given a date when a fix or updated driver will be available.
