Hi all,
We are developing USB host controller for LPC17xx.I would like proper
guide from urs.Here is my Quries
1.Is there any sample code frm(NXP etc)?
2.What are the documents have to refer for write USB host controller?
3.Pls give me the steps i have to follow?
Note:I have already developed UART driver.We will have(LPC) to connect with
USBDatacard.
Anyone have already developed,pls share your experience.
--Thanks for your help in advance.

Google is your friend, search for 'lpc21xx usb host code' and you will
find over 200,000 replys at least a few of which are helpful.
There is an NXP example document

Hi,
You will need OpenHCI specification for USB host registers and how it works: http://www.compaq.com/productinfo/development/openhci.html
Then check NXP OpenHCI for MSD class example code at:
http://ics.nxp.com/support/software/usb.host.msc/
If you are not expert in USB or not having USB analyzer at hand, better put it off. It's not a trivial task.

Take a look @ our mx-LPC1768-S
.
Hope this helps.

Hi,
I have enumerated my USB modem and read modem configuration parameters
from LPC.
There is two interfaces(modem,Mass storage) and each using two end points with
Bulk(in/out) transfer types.
I can send AT commands using bulk endpoint transfer type and read response using
bulk transfer type.Am i correct???
But if modem send any asynchronous response(incoming sms,incoming call),How can
host controller knows or read that response??
I thought modem supports interrupt transfer endpoint descriptor for reading
asynchronous modem response.But it didnt support interrupt transfer endpoint
descriptor .
So How can host controller read modem asynchronous response or notification???Is
it possible to use Bulk transfer type??
Pls share your experience and knowledge and guide me???
Thanks in advance.

Most of source code of mx-LPC1768-S ( http://shop.ngxtechnologies.com/download/sample_code/LPC1768/mX-LPC1768-Stamp.zip ) derive from NXP USBHostLite for LPC17xx, distributed on
http://ics.nxp.com/support/software/usb.host.msc/

Sound like the modem interface is a vendor specific, apart from common CDC.
To confirm it, can you post the descriptors on the modem?

Hi
I am trying to download the files from the links below and the ones from the NXP site for the LPC2468 comes up with file corrupted. It supposted to be 1.2M but the downloaded file size is 250K.
A lot of NXP downloadable files often are corrupted.
Any help on this
