Here is the latest - I tried to plug in a USB 2.0 hub between the newer Macbook Air and the charging cart - still adb devices displayed only eight tablets.
adb version revealed 1.0.29, so I downloaded the newest, 1.0.32, and there was no change. I saw one post where someone plugged in a tablet into their problem laptop and it installed the older driver, so I plugged a tablet directly into my Mac and tried again. Same result. Details from About This Mac - Built-in USB - AppleUSBXHCI About the cart: USB2.0 Hub Product ID: 0x0608 Vendor ID: 0x05e3 (Genesys Logic, Inc) Version: 32.98 Hub: Product ID: 0x2513 Vendor ID: 0x0424 (SMSC) Version: b.b3 We have six trays, each of which old eight tablets. Any other insights/ideas welcome. Thanks.
