I made a board using the LPC1830. The USB0 not connect in HS, just plug in FS.

The same program in a LPB1857 Hitex board plugs into HS.

Tests done as Host and  Device mode. They work at Hitex board in HS, but in our board only work in FS.

It would be hardware problem?  The tracks D+ and D- have no resistor. Were made with balanced (equal length and parallel) mode.

Please can someone help me?
