![]() ![]() ![]() Now i am trying with high speed flashdrive device but still not able to get the device descriptor of the device. Thanks Tsuneo & keith for providing the info that low speed devices will not work when associated with HUB using PIC32 starter kit. ![]() While operating in Host mode and attached to a low-speed device through a full-speed USB hub, the host may persistently drive the bus to an SE0 state (both D+/D- as '0') which should be interpreted as a bus Reset condition by the hub or the host may persistently drive the bus to a J state, which would make the hub detach condition undetectable by the host. this will result in not being able to communicate correctly with the low-speed device.Ĭonnect low-speed devices directly to the application and not through a USB hub. While operating in Host mode and attached to a low-speed device through a full-speed USB hub, the PRE signal may not be generated correctly. Because the device is low speed and the hub is full speed.īecause of silicon bug, PIC24 and PIC32 host can't work with any low-speed device under a hub. ![]()
