Accepted Answer0I went and got a hub and the packaging says USB2,0 and the same thing happens. It is possible the the packaging is wrong. The port does work because I have tried it with a usb2.0 flash drive and it works. Is the problem that the igep usb host port only operates at usb2.0 and the hub are at a different speed?
Accepted AnswermcaroOffline0No if you use a USB hub 2.0 in other case it not work if your device it\\\'s full or low speed ... I left here for your information the OMAP errata manual information: [url=http://www.ti.com/lit/er/sprz319d/sprz319d.pdf]http://www.ti.com/lit/er/sprz319d/sprz319d.pdf[/url] Page 29:
As shown in Figure 6, USB Port 1 and Port 2 can be used to connect to external high-speed PHYs which include a ULPI port. However, in this case, the external USB PHY must be able to accept a source clock generated by the DM37x high-speed USB controller. Also, in this usage model the USB ports cannot support full-speed and low-speed operation. Therefore, using this approach, USB Port 1 and Port 2 cannot provide a fully compliant USB 2.0 Type-A receptacle; a high-speed USB hub would be required in this case; please see Figure 7.Regards Manel
