Thanks to all that have replied to this problem. The problem has been solved with a new Mini USB to type C cable. A lot of confusion regarding compatible comm port, hardware, software, and USB devices. Hopefully to clear the air I have found the following: 1) The Dell 13 XPS 9305 works with Win 11 and the USB 3.2 type C port 2) The Garmin GPSMAP 64S is compatible with the above config. 3) The USB type C 3.2 to Mini B cable for GPS, game controller and legacy USB peripherals must also support Hi-Speed USB 2.0 data transfer 4) The Garmin GPSMAP 64s can be forced into USB Mass storage mode during start up. Go to "gpsrchive.com" 5) I do not know if my original cable was bad or did not support Hi-Speed USB 2.0 data transfer. At any rate it did not communicate with Garmin. 6) Really got bumm information from Garmin tech support that Garmin device did not support USB 3.2 Thanks again, jerrymac

Yes, it is running Win 11 from Dell. The problem shows up when first connecting the cable to the Garmin, starts showing the Garmin logo in the normal start up sequence, then instead of going to the mass storage mode and showing the USB symbol it goes right into the normal run mode. I tried connecting the laptop to an external Western digital HD and it seemed to work fine showing the root directory but did not try writing to the drive will try that. From that I assumed that the cable was OK. I also have a Dell desk top running Win 11 with type A USB and it loads Garmin OK. The USB cable I got from Amazon description reads as follows: Mini USB to Type C cable, Ancable 3-ft. USB C to Mini 5-pin cable charging cord Support sync data for compatible with digital camera, MP3 player, GPS. The I was guessing that the "support syn data was r/w maybe not? Any other thoughts?

Just bought a new Dell 13 9305 to my surprise it only has USB type C 3.1 comm ports. which is not comparable with my Garman gpsmap 64s . After getting new cables to connect to computer it displays "cannot recognize connected USB device". Talked with Garmin tech. and stated that the Garmin GPS does not have a lookup table that the type C protocol recognizes. The problem is in the Garmin hardware with no fix or workaround. Anybody else have this problem or better yet a solution? jmac9900@yahoo.com
