USB Printer does not enumerate

Hello everyone,

We are using LPC4357 controller & with USB host we are trying to print on HP Office jet 6000 printer.

Verified that it supports PCL 3 GUI & it is also able to print on our older systems (Fujitsu micro controller based system).

Now with LPC this printer is unable to enumerate & while the configuration is being set it gives set up & queued status.

But same code works on HP Office jet K7108.

The point where it gets stuck is below

We have used LPC open as reference & till Z character on UART we are able to move.
Marked below with comment.
