(As PTP, only the "Galaxy Tab 2" device appears - no Composite, no Modem.) I have tried, however, connecting it as PTP, and it still connects as USB 1. On the Tab, the USB support has a switch between PTP and MTP, the latter being the default, and the preferred mode for me (as I'm usually hooking it up for music synch). It appears as a threesome: a top-level "Mobile USB Composite device" with two subs: "Galaxy Tab 2" and "Mobile USB Modem." (I have no idea what the modem device implies or how I might use it, but I don't care about it either: I just want the Tab to reliably connect at high speed.) The Tab shows up under an OpenHCD node, unsurprisingly. (In Device Manager, I'm using View|Devices by Connection.) My high-speed thumb drives, external disks, and iPod all show up as subnodes of the "Enhanced" controllers the keyboard, mouse, and USB speakers under the "OpenHCD" ones - and this is true no matter which ports these devices are plugged into. There are also five "Standard OpenHCD USB Host Controller" nodes, which I have determined are virtual USB1 controllers embedded in the "Enhanced" controllers.
In Device Manager, there are two "Standard Enhanced PCI to USB Host Controller" nodes which are the actual high-speed controllers. (Every mobo reference I've seen in reports on this has been for Asus, but of course most reporters aren't reporting that info at all.) The Windows 7 installation is just a couple weeks old (I had a disk crash) but I saw the same warning on the WinXP/64 that was installed previously. I'm not sure what the chipset is the CPU is an AMD Athlon 4850e, but I've seen this message reported for non-AMD systems. It's an ASUS M3A78-EMH mobo from late 2008. In fact, every USB port (there are ten) on this system is USB2. That popup is telling me that the device is USB2, but that it thinks I've connected to a USB1 port. (The first time I did, it was the first time I connected the Tab the second time I did, I was fiddling around and unplugging/plugging in again.) I just don't know what to do to get that high-speed transfer. The two times I've been able to get a high-speed connection, the transfer has occurred at the expected speed. When I plug my Galaxy Tab 2 (7" / Wi-Fi only / Android ICS) into my Windows 7 64-bit machine, I (almost always) get this warning popup that "This device can perform faster."Īnd in fact, transfers onto the Tab in this mode are slow. *BOOT INTO RECOVERY BY PRESSING POWER+HOME+VOL UPI've been doing a lot of research with no reasonable solution. *Finally click on the Star button and wait for few seconds until Odin process and show you the notice Pass in green and completely restart the tablet, click Exit to exit Odin. * Check The AP box and locate the unzipped file TWRP file 5 * Run Odin v3.09 and connect tablet, The box in odin will turn to light blue box ID: COM
