Introduction

This constitutes Amendment No. 6 to the statement on Schedule 13D, filed on behalf of TL Investment GmbH, a limited liability company organized under the laws of Germany (“TL Investment”), Bernhard Bruscha, a citizen of Germany (“Bruscha”), and Manfred Rubin-Schwarz, a citizen of Germany (“Rubin-Schwarz,” and together with TL Investment and Bruscha, the “Reporting Persons”), dated November 10, 2008 (as amended, the “Statement”), as amended by Amendment No. 1 thereto, dated December 8, 2008, by Amendment No. 2 thereto, dated June 12, 2009, by Amendment No. 3 thereto, dated August 19, 2010, by Amendment No. 4 thereto, dated August 19, 2010, and by Amendment No. 5 thereto, dated August 11, 2011, relating to the common stock, par value $0.0001 per share (the “Shares”) of Lantronix, Inc. (the “Issuer”). Unless specifically amended or modified hereby, the disclosure set forth in the Statement shall remain unchanged and capitalized terms used herein but not otherwise defined herein shall have the meaning as set forth in the Statement.

Item 3. Source and Amount of Funds or Other Consideration.

Item 3 is hereby amended and restated to read as follows:

An aggregate of 3,383,869 Shares (the “Pre-IPO Shares”) were transferred by Bruscha to TL Investment on January 23, 2008, which Shares of the Issuer’s Common Stock were acquired by Mr. Bruscha prior to the initial public offering of the Shares.  Bruscha has previously filed statements on Schedule 13G; however, the Reporting Persons filed a Schedule 13D pursuant to Rule 13d-1(f) under the Securities Exchange Act of 1934, as amended, on November 18, 2008, because beneficial ownership of the Reporting Persons exceeded 20% of the Shares outstanding and the Reporting Persons had acquired an aggregate amount of Shares greater than 2% of the Shares outstanding in the preceding twelve months.

The aggregate purchase price of the remaining 808,818 Shares beneficially owned by TL Investment is approximately $2,560,471.

The source of funding of the Pre-IPO Shares was personal funds of Bruscha.  The source of funding for the remaining Shares was furnished from the working capital funds of TL Investment.

Item 5. Interest in Securities of the Issuer.

Item 5(a) is hereby amended and restated to read as follows:

(a)           The aggregate percentage of Shares reported owned by the Reporting Persons is based upon 10,581,235 Shares outstanding, which is the total number of Shares outstanding as of October 28, 2011 as reported in the Issuer’s Form 10-Q filed with the Securities and Exchange Commission on November 14, 2011.

As of the close of business on December 6, 2011, TL Investment owned directly 4,192,687 Shares, constituting approximately 39.6% of the Shares outstanding.  By virtue of their relationships with TL Investment, each of Bruscha and Rubin-Schwarz may be deemed to beneficially own the Shares owned by TL Investment.

As of the close of business on December 6, 2011, Bruscha beneficially owned 87,537 Shares underlying Stock Options that are exercisable within 60 days of the date hereof which, together with the 4,192,687 Shares owned by TL Investment that Bruscha may also be deemed to beneficially own, constitutes approximately 40.5% of the Shares outstanding.
